Ever had the urge to play something old? Something you once thought you were done with, and yet a part of you misses the fun you had and you want to play it again?
 
For me, it's either EndWar, Uncharted 2 or Sims 3. From time to time I get that weird urge to just play one of those three again, even if I know there's a deadline for me to meet and a painting/animation to finish. Most of the time, I don't give in; I need those hours or else I'll never get any work done. However, when I do give in, it all feels just as good as the first time I played the game. 
 
While EndWar isn't a strategy game that I'd call 'excellent', I love the way you view the battlefield, 'on the ground' with the troops and hearing the individual voices of every unit group's leader. The in-game chatter between infantry is a neat touch, even if it sometimes gets drowned out by explosions and such. The game's got problems for sure, but it's fun to play again. 
 
Uncharted 2 is a different sort of beast: The whole game is so bloody beautiful, and full of so much detail that I end up getting inspired to draw or paint something when I notice a cool little detail about the locations. The world of Uncharted 2 is one I'm happy to come back to, mostly because of the fantastic scenery.
 
Sims 3... is an enigma. I can't explain what it is that I like about it, especially considering I got sick of Sims 1 and skipped on Sims 2. Maybe I like the 'Traits' feature, giving sims weird combinations of traits like 'Evil' and 'Friendly', or 'Loner' and 'Romantic'. Maybe I just like the goofiness of the Sims universe, a world where an Insane sim can go fishing at the public swimming pool AND ACTUALLY CATCH SOMETHING. I'm not really sure, but I always find myself playing again for a half-hour to an hour, once every week or so.

What about you? Do you have a game or a set of games you find yourself playing again a long time after you thought you're finished?
