David Allen (born July 30, 1972) is a video game designer and entrepreneur who is most recently known as the creator of Alganon, a fantasy based MMORPG developed by Quest Online, a company he co-founded in 2006.

Born in Denver, Colorado, Allen grew up in Bellevue, Washington where he actively played on the PLATO network, beginning of his interest in online gaming and programming.

The sequel was a more evolved version of Mordor called Demise: Rise of the Ku'tan (released 2000).

While finishing Demise, Allen created the concept for the MMORPG called Horizons: Empire of Istaria and founded Artifact Entertainment in 1999 where he proceeded to raise capital and build the game, relocating to Mesa, Arizona in the process.

He founded Pharaoh Productions later in 2001 where he designed a game called Dominion which was a mix of MMORPG and Diablo play style, but featuring dynamic content.
