b. Will Wright
Will Wright is a founder of Maxis, an Electronic Arts subsidiary, and creator of the Sims. He is the best-known guru in game design, partly because the Sims is the best-selling game of all time for personal computers, but more significantly because he is so articulate about what he does and how he does it. He gives a lucid account of the attributes behind well-designed play.
