In general I don't do a whole lot of replays once i'm done with a games. I like RPGs, but I played Dragon Age Orgins with like 4 or 5 different characters and while I loved it I just do see myself going back to it again. I feel like I've see everything that game has to offer and thats the way I do most RPGs I keep playing them until I'm sick of looking at them then I sell them or put them away for good.
Why do I always seem to go back and play DMC 3? Well I have always loved that series and in my opinion 3 was the best. The first few times I replayed it it was to get S rankings on every mission in Heaven or Hell mode. Now I like to replay the game every once in a while to see if I can still do it.
Although now that I have Bayonetta, I might not play Devil May Cry 3 any more and instead try to get all platinum ranking in Maximum Climax mode. You know what I think I need to go work on that now.
