Dune

A weird strategy/adventure hybrid slightly truer to its source material than the much more famous Dune II.

Unused Texts
The end of the game is over when entering the House Harkonnen, there are three characters, the Baron Vladimir Harkonnen, Feyd-Rautha and Emperor Shaddam IV. But it is not possible to talk directly with them. However, there is a strange way to be able to talk with a game bug or a hex editor. If the House Harkonnen is changed sietch or other place, it is now possible to speak with the three characters enemies to prevent activating the scene of the end of the game as if it was originally planned, it is impossible to ask one of three characters to follow you.

Demo Graphical Differences
A rolling demo (same demo plays at start of retail floppy version) of the PC version of Dune features a couple of minor graphical tweaks, as well as a different face for Paul Atreides instead of the twitchy-nosed Kyle MacLachlan likeness we ended up with.

It's worth noting that in the final game, Paul still has his demo hair in the desert kiss scene.
