A game idea is worth investigating when you can explain what players will experience that they cannot get in quite the same way from nearby games—and test that difference with a small prototype. Distinctiveness is a reason to investigate, not proof that a game will sell. Your idea does not have to be unprecedented; it needs a clear, relevant player-facing difference that your team can realistically make.
What does “distinctive enough” mean?
Distinctive does not mean that no other game shares your genre, setting, mechanic, art style, or audience. Most ideas have neighbors. A useful test is whether a player can understand the particular experience your game promises and why its combination of play, audience, theme, systems, and execution might matter to them.
That difference can be a new relationship between familiar elements rather than a never-before-seen mechanic. Two games might both be strategy games about exploration, for example, yet ask players to make meaningfully different decisions or deliver different emotional experiences. By contrast, changing only the setting or visual treatment may not change what players actually do or feel. The important question is not whether you can describe a difference in a pitch, but whether that difference shows up in play.
Keep three judgments separate: whether the idea is distinctive, whether a plausible audience might care about the distinction, and whether the team can make the game. A positive answer to the first question does not settle the other two. GDC’s 2016 session overview, “Deciding What to Make: A Greenlight Process for Commercial Indies,” by Adam Saltsman of Finji, describes commercial greenlighting as a way to hedge risk, not guarantee financial success. Neither originality nor a lack of obvious competitors establishes that a game will sell.

How can you describe the idea clearly?
Write down the playable promise
Before judging originality, make the idea concrete enough to compare. Write a short description of:
- What players do: the recurring actions, choices, or interactions at the heart of play.
- What they are trying to do: the immediate objective and, if relevant, the longer-term goal.
- Who you expect to enjoy it: the intended player, described through preferences or motivations rather than simply “everyone.”
- What experience you want to deliver: for example, a particular kind of tension, mastery, discovery, cooperation, or expression.
- What defines the concept: important mechanics, systems, features, setting, and story elements.
HM Revenue & Customs’ UK manual on distinguishing initial concept design from later development lists concept, gameplay, features, setting and story, target audience, requirements and schedule, staff, and budget estimates among the elements often outlined in a pitch. Treat that list as a useful concept-stage checklist, not a required pitch format or general tax advice. For this decision, its value is practical: a promise that has no defined audience, production assumptions, or account of the gameplay is too vague to assess well.
Turn the difference into a player-facing sentence
Once you have a playable promise, try this working sentence: “Players who like [reference experience] will get [specific different experience] because [core mechanic, system, or structure].” For instance, the sentence should identify what the player experiences differently, not just announce that the game is “fresh,” “unique,” or “innovative.”

If it takes several paragraphs to explain what changes for the player, that may mean the idea is not yet focused enough to evaluate. If the sentence sounds clear but the prototype cannot demonstrate its claim, the promise still needs work.
How do you compare the idea with nearby games?
Search for meaningful neighbors
Build a short list of games that overlap with yours in one or more important ways: genre, core mechanic, theme, player motivation, or presentation. Do not restrict the search to games that look almost identical. A game with a different setting may be a close comparison if it asks players to make the same decisions for the same reasons; a game with similar art may be a weaker comparison if the play experience is very different.

GDC’s Summer 2020 session “Pre-Marketing Marketing: A Guide to Games Market and Competitor Research,” with Victoria Tran of Kitfox Games and Dana Trebella of Spoke and Wheel Strategy, focuses on market research, competitor analysis, and positioning an idea. Use that kind of comparison to understand the landscape and describe where your concept fits. The existence of a neighbor is not an automatic reason to stop, and failing to find one is not evidence of an empty market.
Compare the player experience, not just the pitch
For each neighbor, record what players actually do, what motivates their choices, and what the game makes them feel or pursue. Then note where your own idea is familiar and where it differs. A distinction becomes more meaningful when you can connect it to a specific change in the player’s decisions or experience. “It is set on a moon” may describe a setting; it says little by itself about what play is like. “Players manage scarce oxygen while deciding whether to help other crew members” points toward a playable tension—but you still need to establish whether that is genuinely central and different in your proposed game.
Separate the novelty of the idea from its execution. A familiar structure can still support a distinct experience through its systems or interactions, while a striking theme may sit on top of familiar play without changing much for the player. Do not dismiss a concept solely because it has genre conventions, or call it distinctive solely because it has unusual surface details.
Use a comparison table to expose vague claims
Write down several candidate ideas and compare them on the same dimensions. This is a discussion aid, not a proven scorecard: the sources do not supply a predictive originality score or a formula that tells a team what will succeed.
| Question | What to record | A useful warning sign |
|---|---|---|
| Can you state the player-facing difference? | The specific action, decision, or experience that distinguishes the idea. | The difference is described only with broad terms such as “immersive” or “innovative.” |
| How does it relate to close comparisons? | Which mechanics, motivations, themes, or presentation choices are familiar, and what changes. | The comparison list is based only on superficial resemblance—or ignores close neighbors. |
| Who is the distinction for? | The players likely to recognize or value that difference, and why. | The audience is “everyone,” or the only evidence is the creator’s enthusiasm. |
| Can the defining idea be made? | Technical questions and realistic staffing, schedule, and budget constraints. | A crucial feature depends on an untested capability or an unspecified production plan. |
| What does a small test reveal? | Whether players understand the goal, engage with the defining mechanic, and can describe their experience. | The key distinction exists only in the pitch and is absent from the test. |
These axes synthesize the market and positioning questions in the two GDC session overviews, the concept and feasibility context in HMRC’s UK manual, and prototype and feedback evidence from a 2013 Global Game Jam study. They are for comparing ideas, not assigning an authoritative numerical rating.

How do you tell whether anyone might care about the difference?
Identify the intended audience and the reason your proposed difference might matter to them. A useful audience description says more than “people who like games.” It connects a group’s interests or motivations to the choices, challenge, theme, or experience your idea offers. You do not need to prove demand before exploring an early concept, but you should be able to explain who might notice the difference and why.

It cannot, on its own, guarantee demand or sales. Friends’ praise may be encouraging, but it is not proof that a broader audience will care; similarly, not finding an obvious competitor does not show that customers are waiting for the game. Treat both as prompts to investigate rather than conclusions.
The cited material does not provide a current market-size figure, a sales threshold for a viable idea, or a validated originality score that predicts success. Do not substitute an invented number for evidence. At this stage, the useful question is narrower: do you have a plausible audience hypothesis that can guide what you compare and what you test next?
Can your team make the feature that creates the distinction?
A feature is not a useful differentiator if it cannot be made within the project’s real constraints. Work out what the defining feature depends on, what remains uncertain, and whether the team can investigate it before committing to a larger production effort. Consider the requirements, schedule, staff, and budget alongside the design—not after the central promise has been treated as certain.
HM Revenue & Customs’ manual notes that gameplay can produce a distinctive selling point and that programmers may help investigate whether an aspect is possible and how it affects gameplay. The manual is UK tax guidance in a particular context, so its tax classifications should not be treated as universal development rules. The relevant design lesson is that feasibility and player experience can be connected: a technical experiment may reveal that a feature is possible but awkward to play, or that a simpler implementation delivers the intended effect.

- Identify the part of the concept on which its distinction depends.
- Write down what the team does not yet know about implementing it.
- Ask what that uncertainty means for staffing, schedule, and budget.
- Decide what is small enough to test before taking on the full production commitment.
If an idea’s appeal depends on a feature that cannot be tested or scoped with the resources available for the next stage, the concept may need a smaller expression, a different implementation, or a revised promise. That does not prove the underlying idea is bad; it does mean that a larger commitment is premature until the relevant uncertainty is addressed.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How do you test distinctiveness with a prototype?
Test the riskiest design question, not the whole game
Make the smallest test that allows someone to experience the defining mechanic or promise. A prototype is most useful when it answers a particular question: for example, whether a choice creates the intended tension, whether a movement system feels different in practice, or whether players understand how the central interaction works. Do not build a miniature version of every feature merely because the final game might contain them.
A paper simulation can use drawings, whiteboards, tokens, cards, or other pieces to represent rules and game components. An engine prototype may be more appropriate for testing movement, controls, mechanics, or interface behavior that paper cannot represent adequately. The right form depends on the question. Buying materials is optional and does not validate an idea; simple paper components are useful only if they make the system easier to test.
Distinguish testing a candidate from developing a selected idea
Alexander Zook and Mark O. Riedl’s 2013 study, “Game Conceptualization and Development Processes in the Global Game Jam,” distinguishes between prototypes that test whether an idea is worth pursuing and iterative building on a simple prototype after an idea has been selected. These are related but different activities. If you are comparing several concepts, make quick tests that help expose which central promise works. If you have selected one, iteration can refine its mechanics and features.
Kellee Santiago’s GDC China 2014 session overview, “Prototyping for Innovation: How to Prototype Effectively,” describes prototyping and iterative design as applicable to conventional and unusual ideas. In either case, choose the prototype based on what you need to learn. A polished demo may conceal uncertainty rather than answer it; a rough test can be more useful if it puts the defining decision in front of a player.

Observe what players do and understand
Ask testers to engage with the playable test, then observe before explaining what they were supposed to notice. Look for whether they understand the goal, whether they interact with the mechanic or system that is meant to distinguish the game, and whether their experience matches the intended promise. Afterward, ask what they thought they were trying to do, which decisions mattered, and what felt different from games they already know.
Feedback is evidence to interpret, not a vote that automatically decides whether to continue. A player may misunderstand a prototype because its instructions are unclear; that may point to a presentation problem rather than a failed core idea. Conversely, someone may praise the premise while ignoring the mechanic that is supposed to make it distinctive. Compare what people say with what they do, and revise the test or the idea when the two do not line up.
The Global Game Jam study describes mechanics and features being refined through personal or outside playtesting and feedback. Its figures provide context for those practices, not a population estimate for all game developers: 16,705 people registered for the 2013 Global Game Jam, and 419 responded to at least one survey question. In categorized responses, 127 of 241 mentioned some form of prototyping; the paper reports 22 paper-prototyping and 92 engine-prototyping responses. Those counts are specific to the study’s survey, and its authors caution that response totals and survey structure limit generalization.
The study also reports that 67 of 93 respondents described iteratively building on a simple prototype, while 26 of 93 described quickly testing multiple prototypes before development. Those categories help illustrate the difference between refining a selected concept and screening several candidates. They are survey responses from that Global Game Jam study, not a recommended ratio or a rule for how every team should prototype.
How should you decide whether to continue?
Make a bounded next-step decision rather than trying to declare the entire project a success or failure. Continue to the next manageable stage when the difference is clear enough to demonstrate, relevant to a plausible audience, feasible enough for the team and budget, and testable with a specific next effort. “Continue” means investing in the next question—not assuming that the commercial case is settled.
Rework the concept or its test when the idea seems promising but players do not encounter the intended distinction. Consider stopping or substantially changing course when the supposed difference exists only in the pitch, the prototype does not express it, or key audience and feasibility assumptions are too weak to justify the next investment. This decision rule is a synthesis of the market-research, greenlighting, feasibility, and prototyping material—not a formal industry standard.
| What you have learned | Reasonable next move |
|---|---|
| Players experience and can explain the intended difference; an audience and a feasible next test are plausible. | Continue with a defined, limited next stage that tests the next important uncertainty. |
| The difference is understandable in the pitch, but players do not encounter it in the prototype. | Change the prototype, the mechanic, or the promise, then test the revised version. |
| Players enjoy the test, but the experience appears familiar in the ways that matter to your intended audience. | Revisit the comparison and positioning; identify whether a meaningful player-facing difference is missing. |
| The distinction depends on a feature with unresolved technical, staffing, schedule, or budget risks. | Reduce the scope or test the feasibility question before committing to broader development. |
| The idea has no plausible audience hypothesis and no clear next test that could improve it. | Pause, reshape, or stop rather than treating enthusiasm or an empty competitor search as proof. |
Keep the decision proportional to the evidence. A prototype can answer a design question, and competitor research can clarify positioning; neither proves that a game will succeed commercially. The goal is to make the next investment based on what you have learned, not to demand certainty from an early idea.
