After going back to the drawing board, MGM Resorts has chosen Springfield, Mass., for a proposed $800 million gaming, retail and entertainment district on several blocks damaged by a tornado in June 2011. The company originally had picked nearby Brimfield for its entry into the Massachusetts casino lottery, but that deal fell through. Developers currently are vying for three casino licenses to be awarded by the Massachusetts Gaming Commission. MGM's complex would include a 250-room hotel, 89,000 square feet of gaming space, and about 70,000 square feet for retail and restaurants. No details have been given for possible event space. The plans also call for a 130,000-square-foot dining, retail and entertainment district possibly to be called Armory Square.
