According to Gamasutra’s monthly Xbox Live Arcade Sales Analysis Zen Studios needs to be gearing up for an office party or something. As of the first of this month they’re getting dangerously close to a total of 1.5 million DLC units sold. The physical number (based on leaderboards) on July 1 was 1,484,245 units across all the different DLC packs, and it could very well be that they broke 1.5 million as of today. Apparently folks love their pinball. Major congrats to all the hard-working gang at Zen.
