Activision touts Diablo 4’s fast-selling launch — but what does that mean?

Activision Blizzard is touting Diablo 4as the fastest-selling Blizzard Entertainment game of all time — no small feat for a company that also publishes World of Warcraft, and the Overwatch and Starcraft series. But what does the claim really mean?

The news release that mentions Diablo 4’s success, of course, says it includes both console and PC sales, but doesn’t divulge specific figures.
