According to statistics gathered by gamstat Spider-Man Miles Morales probably sold over 800K in it's first week of release on PS4 alone
Gamstat isn’t a site to view game sales, but one to make predictions of how many PSN users own a game. Even the creators have emphasized on the fact that players ≠ sales, and usually players > sales. So if the site shows that there are 800k SMMM owners, the actual number might actually be quite lower. But it’s understandable. The game isn’t long enough for the price tag. That being said, I can see SMMM to have ~2 million copies sold (physical + digital) week one.
