You mean 1 day of forza? Only a small fraction of players buy the ultimate edition. Still, Forza has never been that big of a seller in the US, so I dont know why you’re expecting it to be.
It's Xbox main territory still. Half of it's sales from recent games are situated in NA.
That's ignoring the fact that the racing genre has shrunk over the course over the last decade, and now is a pretty niche genre, especially in NA. Forza does much better in Europe than it does here.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
