I really don't like Valve myself. The Left 4 Dead games were horrid. Lack-luster graphics. Repetitive gameplay. Annoying companions. Little to no story. It was all about running around shooting zombies in the face. The only possible fun you can have is goofing around with friends. And a game geared solely toward multi-player does not deserve my 60 bucks. And I've heard that L4D2 started out as a DLC that they decided to just turn into a sequel. And its painfully obvious. Its just a rehash of L4D1
