I often see people talk about playing X game Y times because they love it so much. I very rarely ever feel that way about a single player game. Any time I do replay a game, I often end up not recompleting it. I only end up replaying it if it has been a VERY long time. This gen of games seems to make the problem even worse. I love Uncharted 2 and 3, but I'm not playing those games again. Same with Infamous 2 and The Witcher 2. I loved all of those games, but I have no compulsion to play them again. I feel like I've already experienced what those games had to offer, and I see no value in replaying them. I'm not sure if this is because the current gen of games rely more on big action set-pieces or if I'm just getting older to the point that I don't rely on a singular game to keep my interested for months.
And people talking about replaying games like Skyrim just baffles me. After spending 150+ hours doing everything in Skyrim, there's no way in hell I'm going to want to do it again with a different race/build.
