Nothing quite beats the feeling of long-jumping off a little planetoid and seeing Mario orbit around it as gravity slowly pulled him in. It's a small thing, but I had never experienced something like that in video games and Mario Galaxy is full of moments like it. This game was a joy and I still think back on it fondly. One of the most original and delightfully innovative 3D platformers I've ever played. I loved it so much that I even 100%'d it which involved playing through the entire game a second time as Luigi.
