There are a few optional Star Trek wargames rules, over here in the UK, that appeared in the 1990's to make use of the Micro Machines models that were available back then.
I spent a week, back in 1991, devising a one off set of rules for the South Dorset Millitray Society's monthly "Big all members made up game" so that the Earth - Romulan War, based on the Space Flight Chronolgy" interpretation of it could be played as a 20 plus player battle with a fast turn rotation.
Ships moved at sublight on Impulse or Fusion dirves with Warp Speed jumps across the map only being possible if the ship was at 0.99C.
Weapons were Fusion and Photon Torpedoes, Nukes, Particle Beam Cannons, Laser Cannons (of varying grades).
Obviously, in keeping with the TOS timeline and Space Flight Chronology, no transporters.
The Earth and Ear;y Federation Star Fleet vesels were Pollux, Messier, Verne, Horizon (NCC-01 to 08), Marshall and a few others. Playing pieces were siluettes on card.
The Romulans were sublight only and relied of "Sleeper Ships" to cover the distances between Romulus and Rigel (were the bulk of the war is supposed to have happened in the Space Flight Chronology.
The game went very well, with 22 players commanding a starship (or two for smaller classes) and I was asked to set one up again another week.
The scenario was an evacuation of colonist from a planet in the path of an advancing Romulan fleet. My own starship in the game, UNSS Constellation, suffered an early death after suffering a nuke hit to the bridge, loosing control of the helm and crashing into an asteroid.
I still have the rules sat around somewhere.
