I read Ace Combat is just 3 missions and they look like trash.
The graphics on any PSVR game isn't something to brag about. Best graphics I can remember in PSVR off the top of my head are in Resident Evil 7, Moss, The London Heist, and Batman. Even then, the difference is jarring when comparing the graphics on screen to what you see in the headset. It's similar to going from XB1 to XB360 in some cases.
The immersion is more than enough to allow you to ignore the graphics for the most part though.
If ace combat really is just 3 missions then it'll get the bushes treatment until I can find it for $20 somewhere.
Star Wars Battlefront 1 has a single PSVR mission and that alone is an incredible experience that I wish everyone had the chance to try out, especially if you're a fan of the movies.
