Month is a strange one. Destiny 2 didn't seem to light the world on fire like the last one, anecdotally I noticed a lot of Switch stock in my local stores, and the Xbox probably actually had a decent week for Destiny since they dropped the Madden 18 bundle to $249 and offered Destiny (or any game, but really Destiny) for free along with it. I may add in numbers later, but right now I'm thinking Switch took the month, with PS4 having a decent month and Xbox One having a good boost over last month that is likely to crater even further in October with the price of the Madden bundle rising back to $279.
