What Does It Take to Get a Custom Achievement from Valve? 40,000 Games.
Just when you thought your own pile of unplayed games was a monument to poor impulse control, a hero comes along to make us all feel a little bit better about ourselves. Or a lot worse. I haven't decided yet.
A Steam user from Shanghai, known by the handle SonixLegend, has achieved something most of us can barely comprehend: they've collected over 40,000 games on their account. In a shocking and unprecedented move, Valve actually noticed this beautiful madness and awarded them a one-of-a-kind Steam achievement for their efforts.
A League of Their Own
On September 23, 2025, SonixLegend became the sole owner of the "Game Collector: 40,000+" achievement, which came with a hefty 40,279 XP boost for their profile. They are, at the time of writing, the only person on the planet to hold this digital trophy.
And the grind never stops. In the short time since earning this legendary award, they've already added another 29 games to the pile. Their public profile shows a goal of collecting 40,029 games and a mind-numbing 22,137 pieces of DLC.
The Backlog to End All Backlogs
This isn't a new hobby for Sonix. Five years ago, they made headlines for owning over 23,000 games, which at the time constituted a staggering 54% of the entire Steam marketplace. Back then, their DLC count was a paltry 69. It seems they've been on quite the spending spree since 2020.
It's one thing to own half the store back then, but it's another thing entirely to keep up with the firehose of absolute slop and genuine gems that floods the marketplace every single day now. This isn't just collecting; it's an endurance sport.
But Do They Play Them?
Here’s the kicker, the part that elevates this from a simple story of compulsive consumerism to a true work of performance art. After 15 years on the platform, and with a library that would take several lifetimes to complete, SonixLegend's most-played game is Alien Swarm. A free-to-play game.
They've poured over 550 hours into it and unlocked every single one of its achievements. It's the ultimate power move: buying a digital library the size of a small country's GDP and then spending all your time on a freebie.
So next time you feel a pang of guilt over buying another indie darling during the Steam Summer Sale that you know you'll never touch, just remember SonixLegend. You're not a hoarder; you're just an amateur.
