Who needs high tech? The Star Trek: The Next Generation RPG for the Sega Genesis is still one of the best. The SNES game is the same game but with one major difference. The Genesis version lets you save the game on the bridge computer station. In the SNES version, you have to go to a Starbase to save the game and I'd get destroyed while warping to the Starbase to save the game after completing a mission.
Other than that, any of the Starfleet Command games for the PC. They're fun and you can find cool mods for them online.
