In order to help people avoid spoilers, we are tagging games that are mentioned in theories. If you want to look for theories that bring up a specific game, please check the links below.
If a game has been released in English (or has an English announcement), the English title will be the tag used. If it is still a Japanese only game, it will have its Japanese only title. (Trails in the Sky FC, Trails in the Sky SC, Sora no Kiseki the 3rd, as an example.)
As a note, some theories may cross over multiple games.
If you get a 404 error when loading the tag, that simply means that there are no posts for it yet.
