Bill Roper (born March 27, 1965 in Concord, California) is Chief Creative Officer at Improbable. Previously, he was Vice President/GM at Disney Interactive Studios since June 2011,  and headed video game studios and creative and development departments for two decades, including divisions at Blizzard Entertainment, Flagship Studios, and Cryptic Studios. He is also an accomplished musician, and a founding member of the folk band The Poxy Boggards.
Roper worked at Blizzard North and Blizzard Entertainment from 1994 - 2003 and was Vice President at Blizzard North at the time of his departure. He served in senior production and design capacities on the Warcraft, Starcraft, and Diablo series. He also provided voice-over talent for numerous games.
After his departure from Blizzard, Roper co-founded and held the position of CEO for Flagship Studios, the developer of Hellgate: London and Mythos (which was later released by HanbitSoft). In early 2008, amidst rumors of layoffs within the company, the company dissolved and lost the rights to both Mythos and Hellgate: London to Hanbitsoft and Comerica respectively, after it secured financing with Texas-based Comerica Bank to support the continuing development of its franchises. HanbitSoft currently owns the intellectual property rights to Mythos and Hellgate: London.
In November 2008 Roper joined Cryptic Studios as Design Director and Executive Producer of their newest project, Champions Online. In March 2010, Roper was promoted to Chief Creative Officer of Cryptic, replacing Jack Emmert after the latter transitioned to the role of Chief Operations Officer. On August 16, 2010, Roper announced his departure from Cryptic Studios to join Disney.
Roper was brought on to head  the Marvel Franchise games created by Disney Interactive. He was then promoted to VP/GM, Core Games when Alex Seropian left Disney. While in this role, his Core Games group released Epic Mickey 2: The Power of Two and Disney Infinity, the latter quickly rising to high levels of critical and commercial success.
Roper is currently Chief Creative Officer at Improbable.
