Can you give a specific example? I don't mind how minor it is, I just don't know what you mean, even if its just this camera angle is different or the lighting is changed. I thought the cinematography and tone was intact in the remake, the physics are the same as before afaik since its the old engine running underneath the game. I played OG PS2 SotC to death and I felt it to be a brilliant remake, if they didnt add in more ground detail and alter certains areas (Like the forest with the light streaming through and a few broken shrines) I think it would've looked weird with higher quality materials and polygon count.
Or are you more meaning the increase in available technology made it lose its PS2 charm? Like the way they were doing things that aren't really possible on PS2 by using tricks, eg the HDR bloom, the way the distant environment is rendered and how it blends LoDs/meshes as you traverse the open world, with no loading.
