"This is Han Solo Adventures, a fan-made, freeware (it's not a commercial venture, Lucasarts lawyers!) project by Stacy Davidson. It's as close to my dream as we're ever going to get; a Star Wars adventure game based on an earlier version of the SCUMM engine, complete with that timeless, early-90's Lucasarts look.
The story is described as "interactive fan fiction", Davidson saying to expect something "fairly original, loosely based on available background information on Han and his early exploits".'
