They were both amazing games, but in Super Mario 64 I believe I had more fun. Super Mario Galaxy was a great way to show something new for a Mario game and I loved it, but Super Mario 64 had that magic touch. Also, Super Mario 64 introduced me to gaming, so that is another plus.
So my vote goes to Super Mario 64
Currently Playing: Mario Kart 7, Mario Kart 8, Luigi's Mansion: Dark Moon, The Legend of Zelda: Majora's Mask, Super Smash Bros for Wii U
Predictions:
Super Mario Galaxy will pass Super Mario 64 in total sales CORRECT!
