I beat Duke Nukem 3D recently, and it kicked ass. I'm playing Manhattan Project right now and it also kicks ass. I'm looking forward to Duke Nukem Forever coming later this year, and I plan on checking out the older games too, like the original two platformers for DOS and the various home console spinoffs.

The original games kinda suck, as I recall. o. o Manhattan Project looks decent, I guess.

Duke 3D is a blast. One of the greats. I suggest you play Duke Nukem: Zero Hour. None of the PlayStation exclusives really caught my eye all that much, but maybe some of 'em are pretty cool.

Yeah Duke Nukem 3D is a classic. I think I still have that for computer somewhere.

Duke 3D was great, the 3rd person games that came afterward sucked though.

Zero Hour does not suck. You take that back, twist!

A time to kill sucked
Land of the Babes sucked (probably)

Never played 'em but I always thought they looked like a great load of suck.

But Zero Hour on the N64 kicks my anus. Different developer.
