August has been a big month for Microsoft in terms of their Xbox Live Arcade service with the company seeing a 58% increase in unique users purchasing games from XBLA.
This increase in users has also led to a 67% increase in revenue generated by XBLA game sales. This increase is over the previous monthly high. Although Microsoft isn't releasing exact numbers, we're assuming the previous monthly high was 67% less than this August.
August was when high-profile XBLA titles Braid, Bionic Commando Rearmed, Castle Crashers (pictured above), and Geometry Wars 2 were released.
