In Super Mario Galaxy 2, do I have to collect every star on every planet to complete the story portion of the game (I am not trying to collect everything, just what I need to progress)?

If not, what is the minimum amount of Stars that I need to complete the game - and by that I mean reaching the end of the story and (ostensibly) saving the princess?

As I recall, you need 70 stars in order to access Bowser's Galaxy Generator, the last boss stage. Mario Wiki seems to agree.

This is the same number of stars you seems to need in all newer 3D Mario games.

  • and by 3D Mario games, I mean Super Mario 64, Super Mario Sunshine, and Super Mario Galaxy... although now that I look, Galaxy 1 only required 60 stars.
