A Roblox farming game made by a teenager 'in like three days' had 8.9 million players online at the same time—Steam peaked at 11.5 million across all games on the same day

All signs point to the biggest PC game of 2025 by number of players being Grow a Garden, a Roblox game launched by a teenage developer which just hit a peak player count of nearly 9 million⁠—that is to say, all logged in and actively playing the game at once.

That's almost three times more than Player Unknown's Battlegrounds, which holds the record on Steam. On May 21, gaming newsletter Game File published an investigation by Nicole Carpenter into Grow a Garden, including hands-on impressions and comments from its lead developer.
