As of September 2011, he is Head of Development at Denki. Penn claims his magazine background helped him setting up a "Hollywood-style" studio system there:
"It is something that was born of having a magazine background," he explains. "You don't have slippage, you're doing the same thing 12, 13, 14 times a year, so you get more practiced. It's like the notion of repertoire in the theatre, you have these tools, these methods of doing things, whereas in the game development business we always seem to be re-inventing the wheel."
