The Family Tree of Game Developers

Check Your HUD put together this impressive, massive and nearly comprehensive family tree of game developers.

Not sure what else to add, as just looking over it gets a little mesmerizing. The author says it's not a complete family tree, and it's got a few errors ("Infograms" for eg.) I'm sure nitpickers can find many more. But as an original effort, it's damn interesting.
