Welcome to Princes of Arabia, a role-playing game where you will play along your friends as thieves in a fantastic version of ancient middle east, seeking for treasures, wondrous items and adventure in palaces, deserts and tombs.
This game was written for the 24 Hour RPG Movie Mashup Competition hosted in 1KM1KT. The idea was to mix two movies and make a game out of it. I picked Aladdin and Riders of the Lost Ark. From this movies came the idea of tomb riders in Arabia, getting into trouble to find treasures protected by genies.
