I haven't played DOS games much since my win95 pc carked it. But I used to play a lot of the 3D games, such as Wolfenstein-3d Spear of Destiny Doom 1 & 2 (with the various add-on levels you can download) Hexen Quake Heretic And the earlier ones like Commander Keen, Jazz Jackrabbit, and every Apogee-type game I could get my hands on. Because I am a big cheat, God Mode was always turned on. Games made by Windmill. I also have a few thousand other DOS games in my collection.
