Duke 3D is a given, if you've never played it before you should drop everything and do it right now.
Blood is one you should really consider, I like it even more than Duke 3D personally, but it's definitely more down to taste than Duke is.
Shadow Warrior is also one you should play, but I'd rank it lower than those two for sure.
Redneck Rampage is in a weird spot, I'd say that it isn't essential, but I personally love the hell out of it (though the expansion, Route 66, and the sequel, Rides Again, are a lot better)
The only other one probably worth trying out is Powerslave, but the console versions (which are on a different engine and have different levels) are considered to be better.
