Lucasfilm Games, which later became LucasArts Entertainment Company, was founded by George Lucas. The company is most famous for its line of point and click adventure games, a subgenre that it effectively spawned with Maniac Mansion (1987). (This was back when computer mice were not in general usage -- most users pointed and clicked with help of their Joystick.) In Labyrinth (1986), the point and click interface was not fully developed, but it is clearly a precursor to the much more influental Maniac Mansion.
Further games of this type are Zak McKracken (1988), Indiana Jones and the Last Crusade (1989), Loom (1990), the Monkey Island series (1990,1991,1997), Indiana Jones and the Fate of Atlantis (1992), Day of the Tentacle (1993), Sam and Max (1993), Full Throttle (1994), The Dig (1995).
The outtrodden paths were left with the release of Grim Fandango (1998), featuring 3D actors, and ... no cursor to point at things.
