Zeschuk and Muzyka have written blogs explaining the situation.
Muzyka intends to enter the entrepreneurship field, writing, "I believe strongly in the power of free enterprise to enable sustainable change, so my next 'chapter' will likely focus on an entirely new industry, something exciting, different and frankly downright scary – investing in and mentoring new entrepreneurs, and more specifically, the field of social/impact investing."
Zeschuk describes his fading passion for the video game industry, noting that the people he's worked with over the years still inspire him. "After nearly twenty years working at BioWare I've decided it's time to move on and pursue something new. This decision isn't without significant pain and regret, but it's also something I know I need to do, for myself and my family. I've reached an unexpected point in my life where I no longer have the passion that I once did for the company, for the games, and for the challenge of creation."
That "something new" may be brewing craft beer, Zeschuk says.
"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. If things go well, I'll work on other beer-related shows, apps and projects. If not, I'll have drunk a lot of tasty beers and may be back in games or even something else completely different. Ultimately time will tell."
Contacted for further comment, EA corporate communications simply pointed us to the blog post by the two doctors. All EA would say is that both are retiring form the gaming industry and both execs offer heartfelt thanks to their BioWare teams and EA.
