In the 1980s, a shareware space combat game called 'Begin' was released. In short, it's a turn based tactical starship simulator where you command between one and a hundred ships in combat against an alien fleet. The game is set in the Star Trek universe,
Of Course 
logically somewhere in The Old Series (TOS) range, (as determined by the ship names, types, and the warp scale). You can be or fight against Federation, Klingon, Romulans, or Orion Pirates. You can torpedo and phaser ships, and you can tractor beam and even capture ships in battle. It's a lot of fun, and a game can be as quick or long as you want.
