Drew Karpyshyn, the video game writer whose resume includes Mass Effect 1 & 2, Star Wars: Knights of the Old Republic, Star Wars: The Old Republic, Jade Empire, Neverwinter Nights, Baldur’s Gate, as well as several Mass Effect novels and the Star Wars: Darth Bane series, has announced that he is leaving BioWare. He says he left on amicable terms, and he’s going to focus now on more of his non-video-game projects. Having played a large chunk of your games, Mr. Karpyshyn, as well as having read the lion’s share of your books, I can say that we will miss you, and good luck.
Benton Sartore has been reading comic books off and on since his age was in single digits, and playing RPGs since college. His bookshelf is now full of 1960s Marvel Comics, Batman trades, and Star Wars comics, and he's been known to DM Star Wars, Dungeons & Dragons, and Serenity. He's most proud of his DVD collection — Joss Whedon is his master now.
Benton is also an acting editor at In Genre.

Everything I’ve read points to it being him wanting to work on stuff himself and the split, indeed, being amicable.
Personally, I’m excited to see what he comes up with on his own. I really enjoy his work. It’s BioWare’s loss, but with how big that company has become I doubt they’ll even notice.
