A.) Why would it not mean 10 million sales. I think you're wrong.

B.) Darn.

Used copies, people using multiple accounts, gamesharing etc.

Granted it's not going to be a particularly large difference. But total number of players is pretty much always higher than total sales.

But does that work here? If people have multiple accounts, that means they bought those multiple accounts. And how do used copies work for Overwatch? I just feel like it's probably 10 million, and if not that it's very close.
