SMB3.

Kuribo's Shoe.
That fortress that you climbed up into the clouds for Sky Land.
Tanooki Suit.
Frog Suit.
Hammer Bros. Suit.
First Mario to have FLIGHT.
P Switches.
Warp whistles.
First Mario to have a map.
Fortresses, Thwomps, Dry Bones, Boos.
The Koopa Kids.
Airships.
Getting attacked by the sun and killing it with a turtle shell.
Giant Land.
Pipe Land.
Card games.
Multiplayer min-games.
Mushroom houses: "Pick a box. Its contents will help you on your way."

And the best level design of any 2-D platformer ever made. Best secrets too.

One of the single most hilarious moments in the game came when I discovered I could do that.
