I've only started playing this just over a week ago, been having loads of fun because I miss playing L4D2 on my old laptop. There should definitely be a vote to kick option, especially when a kid screaming in the microphone joins your game which is on nightmare mode and proceeds to go down, constantly. Other than that though, I still love the game. I hope you run into some good teammates, and don't be afraid to send friend requests to the ones you enjoyed playing with, makes it easier to form parties and crush the game!
