I add some more important western video game personalities to get the balance right: 
Will Wright
Ken Levine
Trip Hawkins
Bill Stealy
Gabe Newell
Bruce Shelley
Doug Church
Brett Sperry
Peter Molyneux
Richard Garriott
Ken & Roberta Williams
Jane Jensen
Tim Schafer
Ron Gilbert
The most important western developer imo - Sid Meier - has already been mentioned by Rath.
