Wow... so many people were looking forward to this game, now I know why. 
The controls work so well and all the levels are very different. Super Paper Mario on the Wii was great but this Galaxy thing is even better! Finished the game with 105 stars so far and I'm planning on getting the last ones during the coming weeks.
The final fight with Bowser wasn't very hard but the end scene rocked it all nicely. The 9,5 rating is just right.
