Personally, TF2 was the only game I ever did online for quite a while, then my brother moved out, and I had no PC to play it on...
Yahtzee has a good point about it, though, all the new weapons might end up bogging it down. I still say to bring more levels, etc., it keeps things interesting, and it's almost like a TV series, with new episodes and ideas every now and then. But to keep with that analogy, if they ever add more characters or replace stuff without us knowing, I'm ditching that game ASAP.
