Well that thread title wound up being really unclear, but definitely not for want of trying. Anyway, does anyone know if there's like a list or something of games who support online multiplayer platform crossover? Like, games that I could play on a PS3 and my friend could play on a 360 type of thing. Or does that just straight-up never happen? I don't think I've ever seen any sort of discussion on it which is kind of weird because I'd think quite a few people would wonder about that sort of thing.

Thanks!
