John Carter of Mars
De Modiphius, créé par Iskevosi

John Carter of Mars is a roleplaying game that adapts Edgar Rice Burroughs' rationalist, romantic pulp tales of Barsoom. Heroes fight enemies born of lust, ignorance, and tyranny to save their friends, loved ones, and those cultures and places they call home. False gods, lying priests, deceitful nobles, treacherous assassins, and many other cruel adversaries are the biggest threats. These are the types of stories that will feature in the game sessions and campaigns of John Carter of Mars, using a modified version of the 2d20 system also used in such games as Conan: Adventures in a Land Undreamed Of and Mutant Chronicles.

This is an unofficial version.
