Shadow Warrior? I got that a year or two ago when I found a jewelcase copy around here, but it's such an insanely hard game... on the default difficulty I gave up before even beating the first level. I know I'm not that good at FPSes, but still, that game's way too hard. And yeah, the racial humor is unfortunate as well.
All the rest of those games are absolutely worth getting, though... well, maybe not the Blake Stone games unless you really like Wolfenstein 3D (I find the game boring after just a couple of levels, myself), but the others are for sure.
