To quickly collect 120 stars in Super Mario Galaxy, focus on completing the main missions in each galaxy first, as they generally yield the most stars efficiently. Aim for the fastest routes and practice your platforming skills to minimize time spent on difficult sections. Consider replaying levels to gather hidden stars and collect any comets that appear, as they often provide additional stars. Lastly, utilize power-ups strategically to speed up your progress through tougher challenges.
