Gadget: Invention, Travel, & Adventure (or Gadget: Past as Future) is an adventure game designed by Haruhiko Shono and first released by Synergy Interactive in 1993, following his earlier works Alice: An Interactive Museum (1991) and L-Zone (1992). Like Shono's earlier titles, Gadget uses pre-rendered 3D computer graphics and resembles a point-and-click adventure game similar to Myst (1993), but with a strictly linear storyline culminating in a fixed finale. It thus sometimes tends to be classified more as an interactive movie rather than a video game. The story centers around a future dominated by retro technology from the 1920s and 1930s, especially streamlined locomotives and flying machines.
