If the game is something I really enjoy I'll go back and play it again from time to time if the replay value is good. Some games even require you to replay it to unlock more stuff like the Metal Gear games, for instance. I can't tell you how many times I have replayed games like Monster Rancher, Mass Effect, Game Dev Tycoon, BattleTanx, Final Fantasy, and the list just goes on and on. Sadly, I haven't had as much time to replay new games I play as I used to, since I don't have time to play anything outside of the games I review.
