PUBG might be losing some ground to Fortnite, but the game remains a juggernaut. According to Valve boss Gabe Newell, the battle royale game is Steam's third highest-selling game of all time. He revealed the detail during a presentation this weekend, according to IGN.

"You can have a relatively new game like PUBG, and [...] they can capitalize on all the other multiplayer games, and all of the technology, [and] the fact that China is now a huge market for anybody who does PC game development," Newell apparently said. "So PUBG can come out of pretty much nowhere and become the third largest selling game on Steam's history. Their gross revenue over all-time is already number three in fairly short order."
