Modern games today have little to show other than excellent graphics, weapons, etc. One last comment: Duke Nukem 3D was a Game. eduke32 is supposed to support this pack, I haven't tried it though. There's a high resolution graphics pack for Duke Nukem 3D from this duke4net. eduke32 launches a small GTK window with a few options. When copying the Duke Nukem files from the installed directory, remember to rename DUKE3D.GRP to lowercase (p), otherwise you will probably be presented with an error about a TABLES.DAT file missing or something. Then, copy all game files from the installation directory, inside the directory where you copied the eduke32 executables. I successfully installed it using a Windows XP virtual machine in Virtual Box.
Unfortunately, you will need a way to install the game, because the provided files in this page are the installation setup of the game. I used the shareware version (1.3d) and it worked fine.
3D Realms was the software house behind the game. Duke Nukem Forever was announced to be released sometime in the years that have past, but it never actually made it to the shelves of the computer shops. Wired had an article about the dying of Duke Nukem Forever this week. It was a DOS game and its requirements were not that high, even for the standards of that period. I remember playing it sometime in '97-'98 or '99. Do you happen to remember a game called Duke Nukem 3D? Well, it was one of the best games I've ever played.
