I think at the time I added them, I didn't even see that passage there. The tag for FGO wasn't showing up (on an upload that was clearly related to it) when I fetched source, and I saw there were no tags in the wiki so I added them. I don't see why we shouldn't have them there, though. There are a lot of translated tags that are up to the uploader's discretion on whether they're appropriate to tag. We could have a note to that regard in the wiki instead, and the current one is confusing in not really explaining the reason why very specifically (Mikaeri stated it here, but it's not mentioned in the current wiki at all). Wouldn't an artist be tagging their work as FGO if it relates to their experience with that particular game (regardless of the character's origin in the Fate-verse), though?
