While I do agree with Yahtzee somewhat, I still thought the game was far and beyond many FPSes of today. But Yahtzee, your biggest mistake with DNF was playing the 360 version. No matter what Randy Pitchford says, the console ports were rushed hack jobs, the PS3 version less so. But overall? I thought the PC version was pretty good for a game that took this long to make. Something that DNF has that no other game besides Bulletstorm has done for me has given me a sense of adventure. Around the time I was scaling the outside of Duke Burger, I was emerssed in the experience because while the game is chopped into levels, it felt continuous and plausible.
It made sense for the last few levels to be dark and industrial because it's the Hoover Dam, which we had gotten to via traversing the Mojave Desert in a monster truck. The 2-Weapon swap, while I don't mind it and actually sort of like it, doesn't fit with a Duke Nukem game no matter how you slice it. Not that DN5 should go back to 15 weapons on a whim, at least to me. what should the next Duke game do, then? I have no bloody idea. I mean, Duke Nukem Forever is out. That idea alone is surreal enough that making a sequel to it is just plain alien.
Also, I liked the ending, bite me. (Be sure to watch after the credits of the game).
