Eidos Plc, which just raised some $36m with its flotation on Nasdaq has also exchanged contracts for the sale of 75% of its Silicon Dreams game development business for a minimum 500,000 British pounds to a company to be called Silicon Dreams Studios, controlled by Geoff Brown. The business was part of CentreGold Plc, the business that Brown built into a games empire. Brown will become chief executive of the Banbury, UK- based games development business, which was set up two years ago as the cutting edge development arm of CentreGold. Eidos will keep the remaining 25% of the company, which hopes to do 3m pounds next year.
