I spent a lot
of hours playing Team Fortress when it came out in '98 or whatever, it was brilliant and I was an ace sniper.
and I played CSS quite a bit when it came out but I haven't played one-line multiplayer games in a few years.
What Steam games do we all have?
I have all the usuals:
Team Fortress 2
Counter Strike: Source
Left 4 Dead 2
More recent would be:
Trine 2 (haven't finished either yet)
I also have:
Saints Row: The Third - which could be a blast actually.
