anyone else out there playing/getting this? I just beat the single player yesterday on the pc. game is quality from start to finish and I'm really glad I did decide to get it. some obvious tweaks have been made to the source engine and the lighting especially looks really good. there is some great dialogue in the game too I won't spoil any of it but instead say that stephen merchant did a fantastic job. going to go through the co-op soon with either my brother or one of my friends that has it.
