I used to play the first back at my friend's house and it was pretty cool because we had LAN parties all the time. I didn't own it though, but my friend did nag me to get it so I could join in with her other friends to play. (nobody else I knew played, which was strange because a lot of my friends are regular Team Fortress 2 players)
Of course, I waited until the second came out and I was planning to get it, but apparently the only friend I could actually play it with got a job at Disney World so she was much too busy to actually play the game at all.
So yeah, long story short, I don't have it. :'(
