Holy shit, Watchman finally changed his avatar from the default. Anyway, this isn't actually relevant, but there's this adventure game Daughter of the Serpent, a Call of Cthuklkrijhirg-something related, which dwells in the subject of Ptolemaic Egypt from an archeologist's perspective. It may either educate (if you choose to play an egyptologist specialized in ptolemaic era) or give the chills. It's abandonware now so it can be found here for free. Requires some tweaking with DOSBox to work.
