Does this describe you?

So I just had an interesting conversation with me fiance about gaming...Ironic I know. But she brought up a good question. What game do you have 1000 in that you still play for fun. I came up with maybe 3-4 and she brought it on that I complain about the crap of games that I play and such like that. It just brings up the concept of why do I play for GS. Is it all about the games I play or is there an underlying reason I don't have an answer to on why I play like crap. Its brings up the same dilemma in my head from any other console generation. After you beat the game was there really a reason to go back and play it some more? Or were you one of those that once you beat the game there was no real reason to go back to it?
