Eternal Darkness: Sanity's Requiem
Eternal Darkness: Sanity's Requiem is a 2002 horror game developed by Silicon Knights and published by Nintendo for the GameCube. It was produced and directed by Denis Dyack. The game follows the story of several characters across a period of two millennia and four different locations on Earth, as they contend with an ancient evil who seeks to enslave humanity. The gameplay distinguishes itself with unique "sanity effects", visual and audial effects that confuse the player and often break the fourth wall.

Where Eternal Darkness: Sanity's Requiem sits on the grid
The grid places every game in the catalogue on measured axes rather than on an opinion. This is where Eternal Darkness: Sanity's Requiem lands on each map it has the data for, with the share of the catalogue it beats on each axis.
- Year
- 63ahead of 16% 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 Eternal Darkness: Sanity's Requiem
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.
