Stellar 7 and its better sequel Nova 9 are two fun 3D action underdogs that combine furious action with resource management similar to the classic Spectre.Drive futuristic hovercrafts in missions against the evil warlord Drax and prevent him from-- what else?-- controlling the universe. They're fast and fun, although enemy ships could use a bit more brain :) Stellar 7 was a remake of a 1983 game of the same name from Damon Slye/Dynamix, which was never released for the PC. You can see some screenshots of that version here [thanks to Groovis for info].
