I used to have alot of ps2 games, but a few years ago I was so stupid that I pretty much sold every working ps2 game I had. I regret it alot.. anyway, I recently bought Mega Man X8 for the ps2 and that is currently the only ps2 game I have, I also have a few broken ones here and there. I'm hoping to get more sometime soon because the ps2 certainly has a lot of good games!
