Michael J. Stemmle (born in 1967) is a computer game writer, designer, and director (sometimes designated as a "project leader" in LucasArts parlance) who cocreated some of LucasArts' adventure games in the 1990s and early 2000s (decade). He was also an incredited script doctor on some non-adventure games.
He joined LucasArts after graduating from Stanford University, where he honed his comedy skills writing halftime shows for the Stanford Band and skits for the annual stage musical Big Game Gaieties. After 14 years at LucasArts, he left following the 2004 collapse of Sam & Max Freelance Police and after a period of freelancing, joined Perpetual Entertainment, working as Story Lead for Star Trek Online. In February 2008, he joined a number of other ex-LucasArts employees at Telltale Games.
