I agree, Wolfenstein 3D does not hold up today, it's just too archaic and limited for what it is. It's valuable and interesting as the start of a genrew, but otherwise it's skippable.F-I-D-O said:Doom
Doom 2
Star Wars: Dark Forces
(Hey, I like what I like)
XCom: UFO Defense is definitely still one of the best tactics games.
Ironically, I don't think Wolfenstein3D holds up too well because it's a very slow pace compared to the Doom series, with less weapon variety and more bland level design.
There are certainly others, but these games come up whenever I think of "Great" games anyway, so they certainly hold up despite their age.
I'll echo the Doom games and throw out Duke Nukem 3D, that's still a great shooter.
Rise of the Triad is pretty rad to, Shadow Warrior is pretty fun to. There's a horror themed one thats good to but I can't remember the name right now. I think they were DOS games, or at least DOS compatible. I didn't really have a DOS PC so my experience is limited.
