I like how people are already taking cheap jabs at Quake4. Like they are so damn angry about Doom3 that they will now take jabs at every game that utilizes the engine. Going to take some jabs at Prey next? You realize these are all different developers right?
Raven is responsible for: Xmen Legends, Jedi Knight / Jedi Outcast, Soldier of Fortune, Heretic 2, and Hexen 2. I believe they also produced Painkeep for the original Quake game because they started out modding. A major trend in a lot of their games has been utilizing Quake engines to produce really great SP / MP games.
Bleh.
