PS2 (and PS3 now) all the FIFA*s (not PES). I also have *GTA3 but I don’t play much.
Amiga: Elite2 Frontier (the game I played non-stop for 7 years and my favourite of all times)
PC: various games, right now I’m playing CM2010, which is actually very buggy and not that good, and I know it makes me sound like a football freak, but I’m not. It’s just a coincidence. I usually play RPGs, the last one was Gothic 3.
