A new Superdata report covering June is surprisingly glowing about the MMO industry. MMOs, combined with social and mobile titles, accounted for $660 million in revenue and increased 13.5% from the month previous. The report praises Elder Scrolls Online as being the key factor for the market growth. The fantasy MMO sold 138,000 digital copies last month in addition to any box sales, making it the third biggest seller for June. The report also notes that the pay-to-play MMO market was up 7% from last year for a total of $50 million. Elder Scrolls Online has been topping the PlayStation charts as of late and was a big seller right out of the gate in the UK.
