Gadget: Invention, Travel, & Adventure (or Gadget: Past as Future) is a videogame or interactive movie, first released by Synergy Interactive in 1993. Gadget resembles a point-and-click adventure game similar to Myst, but with a strictly linear storyline culminating in a fixed finale. Thus it tends to be classified more as an interactive movie rather than a videogame. The story centers around a future dominated by retro technology from the 1920s and 1930s, especially streamlined locomotives and flying machines.
