SCUMM of the Earth

"April 26, 2007 - This year marks the 20th anniversary of the SCUMM engine, the Script Creation Utility for Maniac Mansion, which powered most of the classic LucasArts graphic adventures. SCUMM streamlined the process for coding these intensive, epic games and greatly decreased their development times. IGN recently caught up with the man behind SCUMM, the Grumpy Gamer himself, Ron Gilbert."
