(written from a Production point of view)
Star Trek: Federation Compilation was the name of two different compilation packs that were released by Interplay. The contents varied depending on the region.
The US version included three games: The adventure titles Star Trek: 25th Anniversary and Star Trek: Judgement Rites as well as a demo version of Star Trek: Starfleet Academy that included the first three levels from the full game.
Released a year later, the European version was much more extensive and included five games: the full version of Star Trek: Starfleet Academy and its expansion pack Star Trek: Starfleet Academy - Chekov's Lost Missions as well as Star Trek: 25th Anniversary. Unlike the US version it also included two games from MicroProse: Star Trek: The Next Generation - A Final Unity and Star Trek Generations.
