Yeah... I wish people still played UT or something. 2k4 is probably the last time I had a lot of fun in an online shooter. I can't do CoD (tried with MW3, didn't go well). There's not a whole lot of other arena-style shooters that are fun for me anymore though admittedly I don't have a 360 for Halo. I have some hopes for CSGO but that's about the only online shooter I think I can get into anymore.
It's kinda funny isn't it? I haven't played in ages but god I was always getting kicked in versus. Nobody seems like they actually want to have fun in that game, they just want to go from A to B to C and finish the map. Sadly I've had a lot more fun just playing single player because people online are dicks.
For a short time I was able to play the original L4D versus without running into jerks and it was a blast. Just sucks.
