Don’t worry I feel the same with zelda ocarina of time even though there is the Nintendo 3ds versión i prefer the Nintendo 64 versión because I have my childhood on those graphics

Its the gamma contrast of the game making ps2 version darker and grittier and the fact that we are playing in a lower fps making the movement of the collosus longer and more slower compared to the ps4 version,

it is mainly low framerate, the colossi feels more clunky and the experience more cinematography , is one case of design choice that's bound with PS2 limited hardware. i think the overral asthetic of the classic , colour pallete and arquiteture is kind ruined by the ps4 remaster just like they did with Demons souls remake, despite both being gorgeous.

Left is the PS2 version and the right is the PS4 remake version
