Trying To Complete Mario Galaxy With Luigi...

It's hard work! I'm sitting at 63 stars now, and while some are ridiculously easy, I swear they ramped up the challenge level on the Cosmic Races by 100%. Everything else is just like I remember it, but I have a feeling I'm in for a long fight.

EDIT: Just found this on an FAQ:

Cosmic comet stars become much harder to get as Luigi. This is because Cosmic
Luigi makes extensive use of long jumps and will be taking full advantage of
the level's features (such as the speed up rings in Sea Slide Galaxy). You
will have to use Luigi's abilities to the fullest to win.

Ah. Great. I'm probably going to hurt myself before this is all over.
