For the 1998 title "Grim Fandango", LucasArts retired the SCUMM engine in favor of a new 3D engine. The GrimE (Grim Engine) technology was created, using the Sith engine as a base and coded using Lua. The new engine resulted in a redesign in control and gameplay: instead of using point-and-click mechanics, the player uses the keyboard or a gamepad to interact with the game. Full-motion video cut scenes are used to advance the plot, stylized to be nearly indistinguishable from the in-game backgrounds. GrimE was also a true 3D engine: characters are collections of 3D-rendered polygons.
