X-COM is a series of computer games, started by Mythos Games and MicroProse in 1993. The first three titles were tactical games while the fourth was an action-based space combat/strategy game. The first installment, UFO: Enemy Unknown in Europe (also known as X-COM: UFO Defense in North America) was written by a team led by Julian Gollop. MicroProse quickly had an internal team create the sequel X-COM: Terror from the Deep. Subsequently, the Gollop brothers went straight to work on X-COM: Apocalypse, which would end up being the third in the series when released in 1997. Soon after Apocalypse, MicroProse was bought by Hasbro Interactive. All titles were developed for the PC, with a few ports to the Sony PlayStation and Amiga.
The Dreamland Chronicles: Freedom Ridge was a cancelled game by the authors of the original game (Mythos Games), claimed to having been “essentially a remake of the first X-Com with 3D graphics”. [Info from Wikipedia]
