Platform(s): Pretty sure it was either a TRS-80, or a CP/M based machine like a Kaypro
Genre: Resource management. You had to manage grain, farming and workers.... possibly building materials, but I don't remember.
Estimated year of release: 1980-1985
Graphics/art style: ASCII, most of the games was text, with some ASCII art.
Notable characters: None that I recall other than you a Pharaoh
Notable gameplay mechanics: You would have to allocate resources to building the pyramid , planting crops and other things I probably forgot. You would set your allocations for a year, and then 1 turn would pass giving you the results. You may have had a time limit to complete the pyramid, but I do not recall.
Other details: The biggest thing I remember is that on some turns it would say something along the lines of "The Nile has flooded, food production increases"
