UnReal 1 iSO Jointly developed by Epic Megagames (now Epic Games) and Digital Extremes, the original Unreal was first introduced to the world as a Doom killer. But after countless delays and the release of Quake, it was briefly written off as vaporware. Some doubted it would ever see the light of day. Fortunately, Unreal was finally released on April 30, 1998 after a then unheard of four to five years of development (the exact figure varies, depending on who you ask).
