Microsoft is celebrating the success of its recent Summer of Arcade promotion, which saw August break the monthly revenue high by 67 per cent. Over the course of the five-week promotion there was also a 58 percent increase in unique members purchasing XBLA titles.

Released titles during the course of the promotion included Castle Crashers, Geometry Wars 2, Bionic Commando, Braid and Galaga Legions.

"At E3, we committed to re-focusing the Xbox LIVE Arcade business, vowing to release bigger and better games while focusing on quality and not quantity," said Marc Whitten, general manager of Xbox LIVE. "The debut of the new strategy proved to be a huge success, with the Summer of Arcade making August the highest grossing month to date. But the focus on quality games doesn't stop with the Summer of Arcade. We have plenty more great titles coming out in the next few months and beyond that we think will continue to fuel this incredible momentum."

Over the coming months the Xbox LIVE Arcade service will see a number of high profile releases, including Portal: Still Alive, South Park and R-Type Dimensions.
