Horus (2002)

From the introduction:

During the Eighteenth Dynasty of Ancient Egypt, a Pharaoh known as Akhenaten replaced the polytheistic old religion of the creator god Amun and the other gods with the worship of the Aten, or sun disk. This, the world's first foray into monotheism was short-lived in our world, its harsh rejection of the old gods fueling an equally harsh return of the old ways with the death of the Pharaoh.

User summary:

Horus was posted as "Version 0.2" in a series of four major forum posts (followed later by a lengthy "errata" post) for the Game Chef 2002 competition. The game was based on a modified version of the Signature system.
