Prior to joining LucasArts, Jeffery worked in a number of marketing, business and development roles for Virgin Interactive and Electronic Arts.
[3] Jeffery's main accomplishment during his tenure at LucasArts was forging new relations with external developers to fully develop the Star Wars gaming IP, such as Pandemic Studios, Planet Moon Studios, The Collective, Raven Software and BioWare.
However, his goal of turning around a creative original IP slump at the company was never fully realized.
According to Jeffery, LucasArts had too heavily relied on its Star Wars license, but successful new IP failed to materialize.
Games such as Gladius and RTX Red Rock did not achieve critical acclaim or great sales; follow-ups to classic LucasArts adventure games, Full Throttle: Hell on Wheels and Sam & Max: Freelance Police were cancelled, to much dismay of the fans.
