It's ok Luke, I was being sarcastic for the most point, although I do keep it alive when it's relevant for those who only visit there (they exist[ed]).
Yeah dippy is right though, any game that isn't Gundam, BB, P4U2, TTT2, xSF4x, Aquapazza (yeah I was surprised) looked to be sporadic at best. But you can't really gauge a game's playability on Japanese interest, just go with what you like, I mean the only reason the Gundam game is that popular is because it's Gundam, if the exact same game had original concept mechs it probably wouldn't be anywhere near as popular.
