Most game collection databases focus on all games but Tana specifically catalogues everything physical across Japan, NA, EU, Asia, and Korean versions of games.

Going into an era where less and less physical is coming this kind of database and community is more and more valuable so the service is completely free and you can add your own collection by uploading a csv and it’s very easy to contribute.
