I've seen a lot of posts on Reddit that you can play Ps3 games on the PS5 using PS Now. Is this true?Yes that should work, just like you can play PS3 games op PS4 en PC using PS Now
The only Ratchet and Clank game I can't seem to find on PS now or the PS store is Tools of Destruction. Is this because TOD doesn't have trophies? The RaC Trilogy has trophies, and it's still not available either.
As far as I know it has nothing to do with trophies. PS Now is a bit like Netflix. Sony decides what games are available on the platform. New games are added monthly, and sometimes games disappear.
Why you can't find it in the PS Store, I have no idea...
