I have played most through to completion, more than once for a few favourites, but Pro Evolution Soccer 6 will always get the most play, at least until Pro Evolution Soccer 7 is released.
I would have PC games, but I can't afford a PC decent enough to bother.
I have no idea what any of this says about me, other than that I get bored sometimes...
