In an
interview with Eurogamer Bungie spokesman (and GamingNexus hater) Frank O'Conner talks about the somewhat tepid response to the graphics in the Halo 3 beta with this quote
"“Well to be honest, we’ve seen them [the graphics] praised too. Multiplayer is by necessity a more sterile iteration of our graphical style and will always be tuned for performance and elegance rather than jamming the screen full of pixels. We think that the final aesthetic look of our game will be judged at launch in September and in part based on the more intense single player spaces. We’re also focused on maintaining the Halo character and atmosphere in our visual design"
Personally I think the graphics are fine and while the extra effects are always nice I'd rather have the killer gameplay we all know and love. I guess we'll see if there will be any improvements when the game is released in September.
