360 wise at the moment I have 68 retail games and 1 arcade compilation disc and 2 working consoles(Plus I'm awaiting the arrival of 3 more 360 games). I also have around 30 PS2 games and 30+ PS3 games.
Well it's sort of broken down into a bunch of different things. You can either have 150 retail games, 100 XBLA titles or 3 or more system. Sometimes though if people are close enough to the games, or have a pretty good collection of games from all consoles then I'll let them join.
