There was a game called Conquest, which was a fantasy game similar to Empire. I recall that you could play various races, Orcs being one of them, Wizards another. It was very detailed, with each square of the map's terrain having ratings for how useful it was. I remember that there was a note in the source or license that the game was free but not allowed to be run on 'PCs'. (I interpreted this to mean MSDOS machines, and was able to get it running under Coherent). This would have been in the early 90s.
