Basically, it took too long. It feels like they kept adding to it with ideas from other FPS' that it feels a mis-mash of great FPS' but in a very bizzare package. They even incorporate puzzles and some design elements of Half-Life and it doesn't feel right when you're playing Duke Nukem instead of Gordon Freeman. The game is still fun but it tried to do too much and couldn't keep up with the competition.
Had the development been more focused and had realistic goals/milestones then it might have worked better. I also think that if it had been released at the start of the gen then it'd be appreciated more. Instead, it's released into a market full of good quality FPS'.
