GamesOA review
A free browser directory for checking PC requirements, Proton support, storage costs, and install logistics.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
GamesOA is a browser-based PC game compatibility directory for players deciding whether a title fits their computer or Steam Deck setup. Its catalog covers 13,587 games and presents minimum and recommended PC requirements, with specific guidance for Windows, macOS, and Linux users. Linux players get Proton compatibility analysis, save-file paths, Steam Cloud information, and performance warnings alongside the core requirements data.
The free model keeps the directory directly browsable without separating core checks into paid tiers. Each game entry can estimate download time from an internet connection's speed and calculate an estimated SSD storage cost from the download size. Those calculations add practical planning detail beyond a basic requirements table, especially for players managing limited storage or slower connections. The published methodology also cross-references Steam, ProtonDB, IGDB, and PCGamingWiki data, with additional compatibility analysis and manually verified troubleshooting guides.
GamesOA fits solo players who want a focused reference before buying or installing a PC game, particularly those evaluating Linux and Proton logistics. It runs in a browser and does not function as a local hardware-scanning application, so readers must compare the listed requirements with their own system themselves. Players seeking automatic detection of installed hardware or a broader game-management tool should consider a product built around local scanning instead. For requirement research, Steam Deck and Proton context, save locations, and installation planning, GamesOA keeps those decisions in one searchable directory.
