A few months ago, when purchasing a key, the Steam platform was indicated as the place of activation. As a result, it changed to Origin by the time it was released. Otherwise, no complaints.
I took a pre-order for two weeks at the best price, I was lucky with this) I was worried, because I had never done this anywhere. As a result, the key came even before the game was released in the official application. Activated a few hours after the release of the add-on, everything is great!
