Im talking about platformers/action-adventure etc

A few of my favourites:

Super Mario 64: the level where you could either jump in the big or small painting, and it would change the size of the srroundings, enemies etc. that was genious

Banjo Kazooie: Treasure trove cove. Music, the secrets... everything was awesome

My favourite though is Gerudo valley from OoT. Everything about that place is just amazing. the music is phenomenal and the overall awesomeness of the whole thing just blows me away every time
