One could not have easily guessed that there would be so many references to Muslims in tabletop role playing games. I certainly did not know about the extend of this phenomenon until I was enlightened by Jabir Lee a few years ago. Here is a list of such games, quoted here verbatim from brother Lee, and the Islamic/Muslim references in these games.

Veil of Night, (Vampire: The Dark Ages)
A sourcebook for playing Muslim vampires during the crusades.
Clanbook Assamite, Clanbook Assamite Revised, (Vampire: the Masquerade)

“Old Man in the Mountain.”
Lost Paths, (Mage: the Ascension).
Book about modern Muslim mages who split from European magicians due to colonialism.

The GURPS fantasy setting. The premise for the setting is that elves accidently summon both sides of the crusade into a fantasy world. Roughly half the nations in the setting are Muslim.
This is probably the one RPG supplement about the Arabian Nights that actually focuses on Islam. Roug guide on running fantasy adventures set in the post-Jahiliyya middle east.
Infinity is a miniature wargame. One of the playable factions, “Haqqislam,” are Muslims who are forced to flee earth and end up founding a nation in space.
