It was originally created to support the two games made with GrimE, as they were the residual adventure games by LucasArts that weren't supported by ScummVM. It was also a word pun, as grime is a residue. It was expanded to support engines from several other games. These games, Escape from Monkey Island, Grim Fandango, The Longest Journey, and Myst III: Exile, are now supported in ScummVM.
