This is one of the few roleplaying books that left its mark on my soul. While I admit the game has its flaws (the trivial relic-hunting being one of them), it is quite unique in its glorification of personal history, hopes and thoughts of every particular character. Meanwhile, I strongly recommend buing this book with the Sothis Ascends and Guildhalls of the Deathless.
The former is and rich and deep cultural research that tells a lot about several eras in human history (also Sothis Ascends shows how to run chronicles stretching from ancient times to near future with the same characters) and the latter is a detailed portrait of mummy organizations.
