In the realm of esoteric statistics, Microsoft announced that over 50 million hours in "games and entertainment" have been logged on Xbox One systems since it launched on November 22. The console manufacturer added that over 415 million Gamerscore points were unlocked via achievements on the system.

Microsoft also noted a few other in-game milestones achieved in individual Xbox One games, such as the number of miles driven in Forza 5 globally (90 million), zombies killed in Dead Rising 3 (three billion), combos achieved in Killer Instinct (150 million) and enemies defeated in Ryse: Son of Rome (186 million).

By comparison, EA announced that over 140 million gameplay minutes were logged in its games on PS4 in the console's opening five days. To add to today's numbers, Sony announced that global PS4 sales exceed 2.1 million, though we're not certain how that translates to hours spent or zombies destroyed or how close that is to the moon when you stack them all, etc.
