Because i'm feeling like it.
Go play Melty Blood, apparently they've done tournaments inside of bathrooms, it was pretty funny when i discovered it... Wait, that's not the important part, lol, anyway, go play it, the game has like 31 characters with 3 different styles of play for each one, oh, and did i say that like 80% of the cast are anime girls? From schoolgirls to goddesses to loli catgirls to maids.
