Warpstar!

From the back of the book: Warpstar! is a rule-light science fiction roleplaying game set within the Chorus of a million worlds that aims to emulate the feeling of old-school British tabletop games of adventure and action in the depths of space. Warpstar! looks to reproduce the themes and feeling of its illustrious predecessors but in a light, quick and simple manner, with a consistent rules set that is easily hackable and adaptable as desired.
