A few days ago, it was announced that The Elder Scrolls Online would be a subscription-based MMO at $14.99 USD a month. Bethesda has revealed that there would also be a real-money store as well. However, the store would not be for advantages, making the MMO "pay to win". Rather, it seems it'll just be a shop for cosmetic items.
In an interview with general manager Matt Fitor, he stated, "There won't be anything like bonus points, but we'll have a shop to buy kind of fun stuff and services too, like name changes and things like that. But it's not part of the core game. Anything in the core game is included in the subscription."
The Elder Scrolls Online will be released next year on PC, Xbox One and PlayStation 4.
