Gatecrasher is a somewhat light-hearted science fantasy game, where magic has been let back into the universe by a careless prospector who triggered a long-dormant gate to another dimension, wherein all the magic had been hidden for many years. The original version uses the Fudge rules, and was published by Grey Ghost Games; the game has been bought out by Domibia Games who are contemplating a new version using D20 or perhaps Action!System.
