The Genting Group got a steal on the Strip land it bought this week to build Resorts World Las Vegas, a 3,500-room Chinese-themed resort. The Malaysian company paid Boyd Gaming only $350 million for the 87-acre site of the imploded Stardust and failed Echelon. By comparison, Phil Ruffin sold the 36-acre New Frontier property in 2007 for $1.24 billion, a Las Vegas record.
