The Valley of the Pharoahs was a 1983 RPG boxed set from Palladium Books. It was a historical game, set in ancient Egypt.
It’s currently available on PDF over at DriveThru.
Honestly, it’s not very well organized. Important details about running the game are either hard to find, or even missing. Another problem is that it’s never really made clear what players are actually supposed to do.
However, the old Palladium art is always nice to look at, and it has enough background about actual Ancient Eqypt to be interesting and useful. (not GURPS Egypt useful, but still)
The box came with a legal sized character sheet, which wasn’t very well designed, so I’ve made my own fillable PDF character sheet.
