Where Mario Party 9 sits on the grid
The grid places every game in the catalogue on measured axes rather than on an opinion. This is where Mario Party 9 lands on each map it has the data for, with the share of the catalogue it beats on each axis.
- Year
- 78ahead of 33% of the catalogue
- Reach
- 42ahead of 82% 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 Mario Party 9
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.
