That paired with the PSVR would be one hell of an experience.
the platform is barely an afterthought in Ace Combat 7. The VR content, such as it is, amounts to a few exclusive missions with no ties to the main story, a VR air show that you can watch from the deck of your carrier, and a hangar mode. What's there is pretty cool, but it's more or less a novelty mode on par with the X-Wing Fighter VR Mission from a few years back.
Note the VR elements are minimal, and not the full game. If buying this for PSVR i'd definitely await reviews, and do not preorder.
Ace Combat 7 Isn't Much of a PlayStation VR Game Anymore
