In two weeks since we've launched, over 10 million of you have played Battle Royale. We can't say thank you enough. https://t.co/v39jBGe9qd pic.twitter.com/pkC7fhdl4K — Fortnite (@FortniteGame) October 11, 2017

Those aren't exactly comparable metrics, since Fortnite: Battle Royale is free-to-play and PUBG retails for $30, meaning the latter has already amassed a ton of money while the latter spins up its microtransaction revenue streams. For an apples-to-apples comparison, though, Epic estimated that 3.7 million people played Fortnite: Battle Royale on Sunday, while PUBG has nearly 2 million daily players according to Steam Charts.

The new kid on the nascent 'battle royale genre' block is seriously challenging the reigning champ -- but PUBG might not take the usurpation lying down. Its studio Bluehole loudly complained about the overt similarities between its game (released last March) and Epic's new spin-off, and even vaguely threatened the latter in a statement when it said the company would "contemplate further action."
