I just bought it last night, and so far I really like it. It seems to run better than the first one did while having better graphics. And the level design is awesome. My biggest complaint is Rochelle, I know everyone is saying the same thing but I think she is the weakest character.
Here is the L4D2 line up.
1 annoying ex convict who is on rare occasion funny - Nick
1 annoying uneducated redneck who is a stereotype - Ellis
1 annoying not attractive female - Rochelle
1 semi cool black guy - Coach
To be honest, they just should have put Lo Wang in there along with Duke Nuke'em, John Matrix from commando, and Summer Glau as the token female bad ass.
If anyone wants to play with me my steam name is thermophilis (display name is eric though)
Haha yeah you're halfway around the world. I do have my own ded. server and really fast internet, but I doubt it would matter with the distance.
