Now whenever one of your retarded friends (all two of 'em) ask you "but does it play Doom?" you'll have an answer:
http://www.itplaysdoom.com/Doom never caught my fancy. It was Wolfenstein 3D that got me hot.
In no particular order, the best 3D Shooters Ever According to Tyson:
Wolfenstein 3D - Classic!
UT2004 - The pinacle of multiplayer deathmatch. The only thing to improve on this is graphics, which this already shines in.
Deus Ex - Best storyline. Ever!
Max Payne - Best storyline. Ever!
Quake 1 and 2 - Gameplay at it's best. Perfect balance of all the elements of shoot-'em-ups.
Halo - Duh.
Oni - The first and only successful combination of guns and fist fighting I've played. Great storyline too.
I'd add Half Life 2 but... *sigh* Shut up.
Any other favorites?
