I'm enjoying the game. It is classic Duke Nukem. I play for a couple hours or so every week when I'm not in the mood for the MMORPG I'm mostly playing at the time or it's down for maintenance, and it's a nice change from those experiences.
It's a better game than Borderlands, in my opinion. Better graphics, more fun. Still more original than most FPS shooters out there, despite having basically not changed in formula or style since the first one. The humor is sophomoric - but there's a place for that kind of humor, and this is the place. I wouldn't and don't enjoy it in an RPG game (including an MMORPG), but I do here.
Yes, it's also dated in how well you can control Duke, and that can be frustrating, just as it was back then. I do wish some things were better, but the fact is I was expecting a game that started being developed long ago to be one that played like that, not one that played like the best of the modern FPS games. It's unrealistic to think the game would have been re-coded from scratch starting a couple years ago, and if you are disappointed because of that, it's your own fault.
