EDITED TO ADD:
Ubisoft plus classic is also going to be bundled in with the two higher tiers. Not the full Ubisoft Plus but a decent selection.
As a long time PlayStation owner I own almost all of these games in one form or another. The only one I want to play but don't own PS3/4/5 is Ape Escape 1, and I think I have a physical copy that should play on my PS3.
I imagine most people who have been with the ecosystem for a while either own them or decided not to buy them because they were not interested.
The classic game selection is especially anemic, but for a service that costs about as much as Game Pass it is not bringing anywhere close to the value. I get multiple games released each month on Game Pass that I want to play, not even including the first party releases I get free, like Psychonauts 2, my game of the year last year.
I would be curious what others think. Is this appealing in its current form? Will it do well?
