Ace Combat 7 is meant to be a PlayStation 4 exclusive, however, Gematsu noticed that the Taiwan Game Software Rating Information board has rated Project Aces' upcoming game for Xbox One.
The page has since disappeared, however, but not before it was discovered and people were curious about what it means. The ratings board isn't usually wrong (apart from one time last year with BlazBlue: Central Fiction) so who knows, Ace Combat 7 may well be coming for Xbox One. Would you like it to?
