Universe
A sci-fi game around interstellar adventure in a free-market Federation (similar to Traveller)¸ featuring semi-realistic high tech and prevalent psionics¸ but with little background information. The system is a complex percentile skill system¸ with the bonus to the roll being the square of the skill. The character creation and combat systems are both particularly involved. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H. Kim"
