“I have decided to hit the reset button,” said Casey Hudson, who after nearly 16 years of development, has officially left BioWare.

“After what already feels like a lifetime of extraordinary experiences, I have decided to hit the reset button and move on from BioWare. I’ll take a much needed break, get perspective on what I really want to do with the next phase of my life, and eventually, take on a new set of challenges,” he wrote in a letter shared with his colleagues. “This is without a doubt the most difficult decision of my career.”

Casey has worked on several game series during his time with BioWare, including Neverwinter Nights, Star Wars: Knights of the Old Republic, and the Mass Effect trilogy. While speaking with colleagues, he spoke of his confidence in both the future of Mass Effect and Dragon Age, saying that the next Mass Effect game is one he believes will “redefine interactive entertainment.”

“Development for the next Mass Effect game is well underway, with stunning assets and playable builds that prove the team is ready to deliver the best Mass Effect experience to date,” he says. “And the Dragon Age: Inquisition team is putting the final touches on a truly ambitious title with some of the most beautiful visuals I’ve seen in a game.”
