The two are taking a break, perhaps indefinitely, from game creation and management. Muzyka is looking to engage in charities and social work, while Zeschuk is going to dive into projects involving craft beer.
"This has been an incredibly difficult decision to make; after thinking about it for many months, I made the decision to retire from videogames back in early April 2012 -- at that time I provided six months' notice to EA, to help enable a solid transition for my teams at BioWare," Muzyka wrote in his farewell letter.
"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," Zeschuk said in his.
The two maintain that BioWare is in good hands and will continue to excel going forward.
