MegaCD was in a time when you could make games for a few million dollars.
New hardware has a much higher barrier of entry these days. It's killing VR.
Some modders do many unofficial VR ports of shooters and whatnot.
Sony should have had a dedicated team doing just that, with the IP owners agreement of course, port and resell these older either PC or PS4 games with a new free VR extension and throw those ported games VR-exclusive in the Plus basket now and then, and or a Plus-VR-Collection for any VR2 buyer.
Bioshock, HL, CoD, Mirrors Edge, Crysis, Portal, Assetto, Project Cars, Dirt Rally1+2, a NFS Collection etc. anything. These might not be super interesting, because old, but if modders do them because it's so easy, just for their own fun, than some others might be interested too and sales might follow and having enough in Plus to convince some subscribers to lay out the money for the hw, might just get the ball moving.
GT+RE and some indies is not enough beyond true VR enthusiasts. Some people won't get a PS5 until a Slim and price cuts happen. This costs more with less games, games average people don't even know about, ie don't care for at all.
I have no doubt that some games are pretty cool, but none have much marketing pull because they look like average ass AA games in videos. Synapse probably being the first VR exclusive with some recognizable art beside the rhytm games. Known IPs though, even if old, have at least some "ah I know that game" and while I would assume most that have the slightest interest in VR have tried any of the options over the years, so know if they want it or not, but I assume a few millions is the ceiling anyway, but imho with this bare minimum lackluster strategy Sony won't even get them and repeat at most the VR1 "success".
I am even kinda opposed VR exclusives. Ports, ports and ports + hybrids for all new games should be easy to develop, with VR being in the design phase all along, but not designed entirely around it, as though that has been much the case and changed games much until now, make VR2 worthwhile and not more niche, an undesired walled garden, than it needs to be.
