I suppose it's preorder price. Full price wil be at least 80.
Could the 70 bucks be because they are not sure whether people will like their woke agenda stuff, if it has any or simply because they want to sell more copies vs too low price and people start to think the game isn't worth it. Speculations over speculations.
