I recently noticed a thread on Gaming Report which mentioned a sourcebook called 'Pulp Egypt' for any RPG. As two of the games that I have recently bought and like are Savage Worlds and Spirit of the Century, this looked too good to be true. Well, I had to take a look, and I'm glad I did. This is a sourcebook by Peter Schweighofer which costs $20, and is a 176 page PDF packed with information on Egypt (some of it in a similar manner to the Call of Cthulhu RPG Cairo Sourcebook) to support pulp campaigns. Having quickly skimmed the PDF, there are suggestions on how to run archaeological, espionage and crime based campaigns, and some excellent material for reference. I think that it will be easier to integrate with Savage Worlds rather than SotC, as the latter is more free-form and co-creative. However, it will add to both if you fancy some Indiana Jones style adventures.

If you feel that $20 is too much to spend on something you've never heard off, there are a number of free scenarios on the site which give an idea of the quality of the material. I recommend this. They can be found at Griffin Publishing Studios' site.
