Hyperspeed
(1991 MicroProse)

Lightspeed and Hyperspeed are without a doubt two of the most underrated space sims of all time designed by celebrated Gunship 2000and F-15 Strike Eagle III designer Andy Hollis. Although billed as "adventure/strategy" games, they are actually space sims with some adventure game elements. Still, categorization quibbles can't hide the fact that they are two of the very best-- with fluid animations, cool ships, and great interface. In all, great space exploration sims that follow in the venerable Elite tradition. Highly recommended.
