Wow, to those who are being total jackasses(*cough*the usual suspects*cough*),

and quit being such utter douchebags. There are some people that ACTUALLY CARE about this sort of thing and not the crap you care about.
Wolfenstein 3D ****ing ruled. I think I liked Doom more, admittedly, but there was a certain charm to Wolf that always brought me back.
My personal favorite DOS games, though, were the game show ports, especially Jeopardy! I used to play that all the time as a kid.
