Team Fortress 2 probably won't die until they do something stupid like...add something people will do instead of actually playing the game. Like...some sort of taunt? or like...a dance that anybody can join in on. Maybe like a conga, but Gabe is too smart, even if he can't count to three, and he'd never do something as dumb as add a stupid Conga taunt. I mean, nobody would even buy it, I'd be surprised if it sold for over 6 ref. But that's my opinion, maybe once people start to do something else instead of actively playing the game...like trading weps for weps maybe, or (snrk) hats? just a thought.
In my opinion, TF2 is a great game. But depending on your criteria, you'll have to decide if it's right for you.
I don't think TF2 will die. Unless they want to hear a word (book) about how much they would suck to screw with a good game. #GGValve
