Neither you or I have played one second of Horizon 2. We've seen nothing but a cypher of the logo of God of War Ragnarok. And aside from a barren desert of Nanite wasteland, nobody has seen any game actually made of "true next-gen" technology like Unreal Engine 5. We can have a discussion about what gameplay revolutions PS5 exclusives such as Astro's Playroom, Returnal, Destruction All-Stars, and Demon's Souls bring to gaming, but I have a feeling that chat will be short...
How can we know what gameplay limitations there are to hate?
Apologies if that came off wrong, I'm not using the word "gimmick" in a negative sense. It's the term for a new twist on a traditional concept, by definition "an ingenious and usually new scheme or angle". It's their novel new invention for the 14th R&C game, and they're building the whole game around it, from story to play mechanics, much as they built Deadlocked around multiplayer and All 4 One around co-op.
But again, mastering the hardware doesn't come from just exclusive work. R&C Rift Apart was able to come together so well so quickly into the lifespan of PS5 because Spider-Man on PS4 and then Spider-Man Miles Morales cross-gen helped build tech equity that they could leverage while building a game that was in concept meant to make creative, specific use of PS5 hardware.
