Super Mario Galaxy 2
Super Mario Galaxy 2 is a 2010 platform game developed and published by Nintendo for the Wii. It was first announced at E3 2009 and is the sequel to 2007's Super Mario Galaxy. Much like the first game, the story follows Mario as he pursues the Koopa King, Bowser, into outer space, where he has imprisoned Princess Peach and taken control of the universe using Power Stars and Grand Stars. Mario must travel across various galaxies to recover the Power Stars in order to travel to the center of the universe and rescue Princess Peach.

Where Super Mario Galaxy 2 sits on the grid
The grid places every game in the catalogue on measured axes rather than on an opinion. This is where Super Mario Galaxy 2 lands on each map it has the data for, with the share of the catalogue it beats on each axis.
- Year
- 75ahead of 28% of the catalogue
- Reach
- 56ahead of 93% of the catalogue
Percentiles are against the games that carry a reading on that axis, not the whole catalogue: counting a game with no figure as a zero would flatter everything that has one. How the grid works.
What readers say about Super Mario Galaxy 2
Reviews written by people who have played it. These are separate from the GamingPickz Score and are never averaged into it: that score comes from thousands of Steam reviews with a sample-size correction, and a handful of unverified ratings would distort it rather than improve it.
