Scripting in Grim Fandango
[The engine] doesn’t know anything about adventure  games, or talking, or puzzles, or anything else that makes  Grim Fandango the game it is. It just knows how to render a  set from data that it’s loaded and draw characters in that set.
[…]
The real heroes in the development of Grim Fandango  were the scripters. They wrote everything from how to  respond to the controls to dialogs to camera scripts to door  scripts to the in-game menus and options screens. […]
A TREMENDOUS amount of this game is written in Lua.
The engine, including the Lua interpreter, is really just a small  part of the finished product.
