It's a Star Trek game (sort of) made by Simon and Schuster Interactive. It allowes you take certain classes of starships and alter the hull with different variations on different sections of the ship, give it a name and registry number, select what systems the ship has, and assign it a crew. Then, you can test out your new ship by sending it on missions. It sounds really fun, but it really ends up being little more than kitbashing with a very limited selection of parts. The missions are even more boring since you don't really interact with the ship once you send it on a mission. You just watch it move around on a map, read the mission update information, and hope that the ship has the proper equipment and crew to handle whatever it encounters. There were three versions of it released, Starship Creator, Starship Creator Deluxe, and Starship Creator Warp II (usually bundled with Dominion Wars, which is how I got it). I read somewhere that you could use the ships you created in Starship Creator warp II in Dominion Wars, but remember hearing about how nobody could get that to work well, if at all. I've never tried it, so I can't really tell how badly they screwed up that function.
