It’s easy to say a game is big. PlayerUnknown’s Battlegrounds, despite the goofy name, is big. But it’s hard to say just how big until it hits some milestone. Like say, surpassing one of the biggest games of all time.

The development team announced this week that its multiplayer game has now passed the superhit Grand Theft Auto V for most concurrent players. The only games ahead of it are Dota 2, Counter-Strike: Global Offensive, and Fallout 4.

Let’s put that in context

None of those are new games, but they’re all huge games. Grand Theft Auto V has continued to rank in the top 10 game sales month after month since it his PlayStation 3 and Xbox 360 back in 2013, and sold well when it hit PC in 2016. Fallout 4 was a hotly-anticipated game when it released. Both of those games hit their concurrent peaks during their first months of release.

PUBG, on the other hand, released back in March and has continued to grow. The announcement that the game would be coming to Xbox One as well was one of the big surprises of E3, along with things like Minecraft getting total cross-platform play because the game has seen such a meteoric rise in popularity. That it’ll surpass Fallout 4 seems like a foregone conclusion. It may not hit the numbers of the free-to-play monsters that are Dota 2 and CS:GO, but it’s still a huge game. When it debuted, it was an entirely new thing, while Grand Theft Auto V and Fallout 4 were huge sequels to huge franchises.

PlayerUnknown‘s Battlegrounds is huge, and it’s still growing.
