Games that let people build things

Jeff
Tunnell
Game maker.

I co-founded Dynamix in 1984, made a bunch of games, then co-created The Incredible Machine with Kevin Ryan. Since then I've started GarageGames, PushButton Labs, Spotkin and Monster Ideas. In all of those years I have not been able to get TIM out of my mind. Millions of kids have played those games. Today we are building PlayWorlds, a web based, much expanded version of TIM.

The idea

After a lifetime of building games, I still can't get The Incredible Machine, Contraption Maker and now PlayWorlds out of my mind. They all give me the same little feeling of satisfaction every time I build something and it comes to life. They are not the most economically viable games to build, but for over 30 years, they have been my calling.

The other lesson came from GarageGames. The engine got people in the door, but the community of makers is what made it matter. PlayWorlds is built on both ideas.
