Yeah, I don’t have the PS Plus Premium thing and idk if it would be available for me to stream them either. So I play the original games on PS3 as the best versions I think (PS5 would be streaming the PS3 versions anyway).

I play ● R&C 1-4 (4 being Deadlocked/Gladiator) on PS3 (HD “remasters”/upscaled versions) ● Size Matters and Secret Agent Clank on PS2 or PS Vita ● R&C Future series (Tools of Destruction, Quest for Booty, A Crack in Time, Into the Nexus) + All 4 One and QForce (which is also on PS Vita) on PS3 ● Ratchet & Clank (2016 reimagining) and Rift Apart on PS5

Overall you can play the entire R&C series apart from the mobile games as long as you have a PS2 (or PSP or PS Vita), a PS3, and a PS5. (Or if you emulate all of them except the latest 2 on a computer (or phone) and either play Rift Apart PC port and play R&C2016 on PS4 or just both of them on PS5).

I agree it would be ideal if they were all just available to play on one console (PS5). Technically I guess with PS Plus Premium you can play every game on PS5 apart from Size Matters and Secret Agent Clank and the mobile games, though I’m not certain if every game that was available on PS3 can be streamed on PS5, but that requires an expensive subscription that not everyone can get.
