Duke Nukem Forever.
Hear me out.
The Hive mission should be muted. The hive style enslavement was in Duke 3D, but we didn't need Duke's jokes during a serious scene. The only line he should keep is when he rages after his girlfriends die. Also, health regen and 2 or 4 weapon slots is wrong.
Now. The game is worth about 20 bucks. It isn't the best game and it doesn't live up to it's development time. HOWEVER, it has a lot of unique things we haven't seen this generation.
The game features lots of random interactivity. That is something that existed in the late 90's, with Deus Ex and Soldier of Fortune. It is refreshing to have the ability to drink water, microwave popcorn/rats, play pinball, shoot basketball, lift weights, etc.
Some of the humor is funny. Yes, the humor is ripped from classic movies, but that doesn't mean it isn't humorous, it just isn't original. Sorry, but shooting a pig cop and then yelling PORK CHOP SANDWICHES is funny for anyone who has seen the GI Joe parodies. Also, this one was multiplayer only, but shooting the jetpack off an enemy and then exclaiming You're gonna love my nuts. is funny to me.
Everyone with a capable PC should buy this game. It is cheap on the PC, with mappable controls and short load times, which were two of the console complaints. Steam throws it up on sale every holiday and it is definitly worth a grab, you get boss fights, unique environments, interesting weapons, and old school charm (sans the hive)
So buy it, you don't have to think it is the greatest game ever, but it is DIFFERENT, and as far as I can remember, there aren't any weapon attachments, perks, or Russian foes.
