This has to be a joke. mw2 has given me horrible headaches. For one, the matchmaking system is a bad idea. Give us pc players the ability to choose servers we play on and the rights to admin them. Hackers are a big problem and since you can't admin the server, you're only options are to leave or deal with it. Another thing that gets at me is the players that find their comfy little spot and then pitch a tent. Maybe I just have too much sense of securtiy with CSS and its gameplay, but thats just my thoughts.
*Edit*
I will admit that I've been having some fun with Search and Destroy
