Dude, awesome list! Sounds like our tastes are at least somewhat parallel. I, too, don't care much for FPS on the whole.
With that in mind, I urge you to try out Half-Life. I'd almost recommend starting with the second one, though that may be somewhat confusing story-wise. The first one just starts off so slow...
Seriously though. Give it a shot. Also, you like Doom...do you like Star Wars?
If you answered "yes" to that question, check out Dark Forces. It was ported to the PS1, but looks & plays much better on PC. It's a pretty shameless Doom clone, but sometimes I feel more like killing storm troopers than denizens of hell. Plus, you get the Wilhelm scream when you fall off cliffs!
