After linking to my Playstation account, only my PS4 games show up and not my PS3 games. Is this to be expected?

curious also.

Curious about this too
Because of that I don't have all my Drakengard/NieR series on Galaxy 2.0! @w@
(Seriously, I find it strange too, since I thought PS4 and PS3 games were handled at the same way on a PSN Account (at least about trophies))

I'd like to add that although my owned Playstation 4 Games are listed, it also shows some games I downloaded on Playstation network while I was using it but no longer have access to, since I am no longer in PSN. Seems the Gog Galaxy Client cannot tell the difference.

Yes, PS3 Games are currently not supported - as the PSN - Integration isn't officially from gog.com, no one knows wether this will be addressed in the future or not

My GOG 2.0 did not detect PERSONA 5. At first I thought because it is on both PS3 and PS4 (I had the PS4 one of course), but my GOG friend got the game on his profile, along with his achievements. So why won't mine show up as well?

Are you able to play the ps4 games with the gog 2.0 launcher?

Apparently not, it's a different hardware platform. You can still add your PS4/PSN games library to Galaxy 2.0 to keep track of your games, achievments, friends etc. in one place.

obviously not

+1 rep thank you for informing me
