Monster Ideas is the game company Jeff Tunnell founded in 2020. The people behind it started Dynamix, GarageGames and PushButton Labs, and made The Incredible Machine, Starsiege: Tribes, the Torque engine and Contraption Maker. Millions of kids have played our games. Today we are building PlayWorlds.
Between us we founded Dynamix, GarageGames, PushButton Labs, Game Dev Castle and 21-6 Productions, and have shipped hundreds of games and products, including The Incredible Machine, Trophy Bass, Social City, Orbz, Tribes and the Torque Game Engine. We work with a community of developers around the world.
