All of those things are far more than what most FPS games out there offer. Now it's all about tactical nukes, killstreaks and generic online fragfests.
Looking at screenshots and videos I can't tell the difference between battlefield 3 and Modern Warfare 3 unless there is a logo attached to the image.
Duke Nukem Forever, despite being steam rolled by "professional critics" is humorous, lots of side mini games, and overall an entertaining game. That was it's goal, and it excelled at it. It wasn't a perfect game, but still more fun to me than the call of duty crap.
The Darkness strayed away from the monochromatic wargames present in nearly all modern FPS games. Because most what you get now, is either a halo or COD rip off.
My opinion anyway. Btw, they also confirmed at comic con a movie of the darkness is in development. Comic book movies don't seem to be ending anytime soon.
