As tough as this is, I have to go with the game that started the Mario games heading this direction. Mario 64
Mario 64 wins 3-2.

Welcome to the Greatest Nintendo Game of All Time contest, first round.
The matchups were randomly decided.
I will put the matches up every other day, and each round will be open for three days (so there'll probably be 2 or 3 matches taking place at any one time). I want to get through the first round as quickly as possible.
ROUND ONE, MATCH NINE
Super Mario Galaxy (Wii)
Super Mario Galaxy is a platform video game developed and published by Nintendo for the Wii in November 2007. The levels in the game consist of galaxies filled with minor planets and worlds, with different variations of gravity the central element of gameplay. The game is the eighth best-selling Wii game worldwide with sales of 12.69 million, as well as the best-selling 3D entry in the Super Mario series. The game received critical acclaim and was a commercial success upon release. It is the sixth highest rated game of all-time on review aggregator Metacritic, having an aggregate score of 97% based on 73 reviews
Super Mario 64 (N64)
Super Mario 64 is a 1996 platform video game developed and published by Nintendo for the Nintendo 64. It was one of the launch games for the console. The game established a new archetype for the 3D genre, much as Super Mario Bros. did for 2D sidescrolling platformers. It is the best-selling game on the Nintendo 64, with more than eleven million copies sold. The game has left a lasting impression on 3D game design, particularly notable for its use of a dynamic camera system and the implementation of its 360-degree analog control. The title is acclaimed by many critics and fans as one of the greatest and most revolutionary video games of all time.
WHO WINS? YOU DECIDE.
