The review scores for Destiny may not be as high as developer Bungie might have liked, but the people who bought it sure are playing it a lot.

In a post to Bungie’s official website, Community Manager David “DeeJ” Dague revealed that the average play session in Destiny is three hours hours on weekdays, and four hours on weekends.

Dague also repeated a statistic that Activision revealed earlier this week, which is that since launch, players have put in a combined 100 million hours into the game. Together, they played 137 million of the game’s activities.

Though the corporation previously noted that it had already made more than $500 million from selling copies of the game to retailers and first parties, since release the game has made about $325 million from individual customer purchases.

“Destiny fans played more than 100 million hours of the game in the first week. That’s on par with the engagement levels of our most popular Call of Duty games, which obviously is an industry leader,” said Activision publishing executive Eric Hirshberg.

Developer Bungie continues to update its shared-world FPS. On Tuesday, it unlocked the first Raid mission for players on level 26 and above, while one day later it doubled the frequency of its Public Events.
