More polygons than gamers ever saw in their whole life up until that point, but still not quite enough of them, in this 1996 id Software’s creation, along with 3D BSPs, lightmaps and a whole bunch of low resolution brownish textures. Thousands of internet multiplayer servers and total conversions followed the release. Two official mission packs and three sequels later the game still lives on.
PS
I might add that my preferred version of the game is actually on the NES (I had the first, non-Alladin version), and that graphics are slightly better in the MEgaDrive (Genesis) version.
A classic IBM PC title, full of cuteness and charm with all of the attributes of the games of the time (such as CGA graphics and a tiny executable). Provided me with hours of fun when I was a little kid.
