The leap from Super Mario World to Super Mario 64. Mario had so much more freedom of where he could go and what he could do.

This is about leaps from one system to the next after the 4th to 5th transition, so starting from N64 to Gamecube, PS1 to 2, Saturn to Dreamcast.

Ok, Super NES to N64. Mario World to Mario 64 best illustrated that.
