Still one of the greatest 3D platformers of all time. Both Galaxy 1 and 2 are great, but what I think puts this one over the edge of its sequel is the more exploratory design in its galaxies.

Freezeflame, Sea Slide, and Melty Molten are my personal favorite galaxies. And the Purple Coin missions are my favorite part of the game, especially the ones where you have to explore across the whole level to find all 100.

Peak Mario.
