When I get bored lately I change class and play entirely different than I normally do. I may be a terrible demoman, but at least it's something different.
I've also learned it's not worth playing if the "cool" people aren't on. If I don't have someone to talk to, I generally spend less time playing (not the worst thing in the world, by far.)
I've spent more time playing
PS2 (anyone remember Sly Cooper?) readin stuff online and getting stuff done around the house. All I know is I can't wait for
L4D. I'll stick around
TF2 as long as the people are there, but if there's some mass exodus to a game I could care less about then it'll just be what happened to me when my friends quit WoW in droves and I'll find something else to do.
If you guys can think of ways to make it more fun for you, I'm up for it. We'll have to do Dustbowl one of these days for sure, since that got the most votes and I haven't played it in forever. If nothing else stick around the forums, makes for something to read from people worth acknowledging
