According to Steam, which can be spotty in reporting this particular metric, I have played Team Fortress 2 for 194 hours. That's probably about right.
Look, I'd like to have played more Left 4 Dead 2, the four-player zombie survival game. I have never been good enough at it to play it online with strangers, and it's no fun playing it alone to get better. All my gamer friends play it on a console, but I'm primarily a PC gamer--even though I did buy Left 4 Dead (1) for the 360 to play with one of my roommates. We only played it a few times (I got a job, actually, and that interfered a lot with our playing), the whole experience just further proving how awful I was at it.
Apparently I kept upsetting some witch or something, though how I was supposed to know there was a witch there, or that I was supposed to turn off my light when my friend turned off his light...I would just need a lot more time with it in order to play with potentially critical strangers, okay?
So anyway: Team Fortress 2 Co-Op mode? Wait a minute...wait a minute...that's flipping great! I'm halfway decent at that game!
What do you know, once again, TF2 drags me back kicking and screaming--and giggling...
