The Virtual Theatre is a computer game engine designed by Revolution Software to produce adventure games for computer platforms. The engine allowed their team to script events, and move animated sprites against a drawn background with moving elements using a point-and-click style interface. Upon its first release, it rivaled competing engines like LucasArts' SCUMM and Sierra's Creative Interpreter, due to its then high level of artificial intelligence. The engine was first proposed in 1989, while the first game to use it, "Lure of the Temptress", was released in 1992, followed by "Beneath a Steel Sky" (1994), ' (1996) and ' (1997).
