Experimental, but still a lot of the core is still there. Super Mario Odyssey was still Mario 64 style, but the addition of enemy possession just gave you a lot more, but Mario himself still felt like a updated 64, it was basically the Mario version of Majora's Mask, which itself still played like Ocarina of Time, just with more gameplay and improvements added. Metroid when Prime was created was still very Super Metroid just with a fist person perspective to make her arm canon work the best in 3D. Even Zelda Breath of the Wild still had lots of Zelda flavor, heart upgrading, 3rd person melee combat with arrows and bombs, main story being about beating dungeons and then showdown with Ganon at Hyrule Castle (just with the linearity removed, although that's not new to Zelda either). Hell, while you may not get a dungeon item you still get a dungeon ability, so that's even still there in a new way Not even jumping was new to Zelda, and I'm not even talking about Zelda II (although Zelda II is a good comparison for this situation, which wasn't exactly a bad game for its time either).
Thing with God of War, which I pointed out a few pages ago and you didn't get with my Castlevania comparison from the other, is with the new God of War it isn't just about the new camera and if the new combat is better, worse, or different, there is also the fact that outright half of God of War is gone. There is no more platforming and scaling objects, or no jumping at all, hell Kratos needs a kid to throw down a chain for him to climb up a tiny ledge now, which is also odd from a story perspective given his past adventures.
If Uncharted 5 (I use this comparison since Ascension went full Uncharted with climbing) came out and was a first person shooter, but now just a corridor shooter without a jump button/platforming/climbing, would you still say that was a good thing if the actual gunplay was better in first person, or would you be mad that the other half of Uncharted's gameplay is completely gone, not reworked or redone, but gone, even if the new first person shooting itself was still good or even better than the third person shooting of the originals?
