Per his blog:
"I am pleased to announce that I am a co-founder of a new company based here in the San Diego area. We’re starting small and growing as needed. Our focus is going to be on bringing some sophistication to casual/social gaming. At some point we will also return to developing MMOs.
After a needed 3 year break from 11 years of working on massively multiplayer games with the large teams, budgets, and 3-5 year development cycles I think this will be a nice change of pace. I’m also very excited to be involved in a genre that is relatively new to me. I look forward to bringing MMO design principles to casual/social gaming."
More information on the specific jobs can be found at his website. If I understand correctly, it seems he wants to somehow merge MMO ideas with Farmville type games. Regardless of some past mistakes, personally I've had a lot of enjoyment from games he's been involved in. So I wish him the best of luck and look forward to seeing what the company team come up with.
