Help, Your collection
Insights
Insights is the second tab on your collection page (Shelf | Insights | Value). It turns your collection into a few charts and facts you won't find anywhere else.
You'll see what your shelf is made of by platform, region and decade, plus a few of the more fun ones, like a day-of-the-week chart, the longest waits between a game's Japanese and Western releases, and which of your games were renamed abroad.
Insights only uses your own collection, and nobody else can see it.
