Upcoming Super Mario Galaxy Speed run.

I am planning to do a Super Mario Galaxy speed run. NOT Super Mario Galaxy 2! The first, less popular game. I am doing a segmented (segmented means I do it in parts where I can save and start over and do better if I need to) Mario 120 star speed run. It won't be done soon, because I didn't really do anything but decide I'm going to do it. Also, I need to defeat Bowser twice, because the fifteen purple coin stars only appear after you defeat Bowser the first time.
