So some found it fun while others have not, tastes are always relative anyway. I personally found it fun, parts I enjoy blowing enemies apart with the shotgun or sniper, aswell as the strategic use of explosives (hitting as many as possible). Pipebombs are realy fun to use rather than a plane grenade as timing is a big part, some of the battles from bombs turrets or rockets have a nice mix between overpowered yet also a challenge. Duke may be corny and a bit of a bad influence, but he is fun, he can go through some really bad event, but instead say a one liner makeing it look like childs play, or complain about his bear.
What did you not like about it Dunbots, or not find fun? Did you play the original Duke Nukem 3D?
I personally don't like realistic shooters, I get a bit bored with Black Ops, but have fun with a powersuited supersoldeir, a gun with a chainsaw, or evil shadow tenticles, and Duke Nukem fits right in with ripping aliens apart with also weapons like a freeze or shrink ray.
