Well, if you count all the Pokemon games, I've probably beaten them more times than all my other JRPGs put together.
Also, I had strange urge recently. See, I had 3 or 4 games sitting in front of me, that I hadn't beaten yet (Final Fantasy 13, ModNation Racers, and 1 or 2 others), but despite this, all I wanted to do was play Bioshock... for the 7th or 8th time. Hell, I probably shouldn't even TALK about Bioshock, since that'll make me want to replay it AGAIN.
