[General Discussion] If you could only play one game for the rest of your life...

I think my fondness for Team Fortress 2 is well-known at this point. A lot of other shooter games settle for a bunch of individuals doing their own thing and possibly winning, but TF2 forces you to collaborate with your buddies to take objectives, even if it's something as simple as "push in behind the uber, guys." The team dynamic adds a lot of the appeal to the game for me, because I love that feeling when you know you contributed to the team being able to do something.

I used to get that in Battlefield, but to a much lesser extent. The 24 person cap for TF2 means you're bound to be able to do something constructive during the time that you play.

If I could count on continued expansions/user generated content, I might pick something like Fallout 3, but I think eventually I'd feel like I'd done everything there was to do in the game, which is the danger in exploration games like that.

Jam it back in, in the dark.
