Recently I've stumbled upon a pre-release demo version of
Warcraft: Orcs & Humans. The date stamp on the installation files (October 4th, 1994) places it about a month before the game's final release. WHile the levels are largely the same, the demo has a few notable differences, including different speech clips for Human units, a static image of the map in the briefing, and different graphics for the Human Barracks:
