Where Ninja Gaiden II: The Dark Sword of Chaos sits on the grid
The grid places every game in the catalogue on measured axes rather than on an opinion. This is where Ninja Gaiden II: The Dark Sword of Chaos lands on each map it has the data for, with the share of the catalogue it beats on each axis.
- Year
- 44ahead of 4% of the catalogue
- Reach
- 30ahead of 72% 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 Ninja Gaiden II: The Dark Sword of Chaos
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.
