-Tighter controls -more interesting worlds and platforming -countless different kinds of challenges and minigames. -Better story (obviously) and voice acting. -Better boss battles, same boss isn't recycled 4 times -More content(?)
Tbh I can't even remember most of the Spyro 3 worlds and it was my favorite PS1 game. The gameplay was top notch, but the worlds just weren't memorable. Mario 64, on the other hand... I can distinctly remember everything about that game.
