When accounting for activity across platforms, 87% of The Blood of Dawnwalker players have played The Witcher 3 - a much higher number than what was reported around the web earlier today.

Gamers play on many platforms throughout the years, and single platform overlap doesn't paint the full picture. To accurately calculate overlap between two games, play activity must be correlated across platforms, as only PlayTracker does.
