Star Frontiers is a sci-fi game produced by TSR during the 1980s. The game was generic to a point but came with its own definite background. The game never really rivaled Traveller although Star Frontiers did pick up a dedicated following of people who preferred its "space opera" feel to the hard science of Traveller.

Players were expected to be "space cops" fighting the aggressive incursions of the alien race known as the Sathar.

The Yazirian race, available to player characters, strongly resembled Winged Monkeys of Oz, and the fictional species was rehashed as Shadow People in TSR's later Dragonlance series of campaign modules. Both species also bear a strong resemblance to the High Martians of GDW's Space:1889 RPG.
