On 18th September 2012 it was confirmed he left the company along with co-founder Ray Muzyka, stating: "I'm not going to be working in games for a while, and there's a strong possibility that I won't be back. After my departure I'm going to be spending significant time with family and friends, as well as pursuing some personal passion-driven projects related to craft beer. The main project I will be working on is a web-based interview show called The Beer Diaries where I interview notable brewers and showcase their beers".
