Yeah, I would have to say that I play for the challenge of completing the goals I set myself, and looking back to when I could only wish for the things that now I have. Understandably, it can seem a bit sad to get happy or get a good feeling inside while playing a game, but I think that it isn't that different from real life really, in that perspective. You want a new job, so you get an education, stick at it, and then look back to the times when you struggled to get to where you are now. Thats my two cents :)
