"In a terrifying milestone for game hoarding, and for the first time in Valve history, a Steam user has crossed the unholy threshold of 40,000 games owned to claim the rarest game collector badge available.

SteamDB rankings show that Steam user Sonix, or SonixLegend in full according to their public Steam profile URL, reached the 40,000 game threshold today, September 23, 2025, making them the first user to unlock the "Game Collector: 40,000+" Steam badge.

Sonix is something of a hidden legend among Steam obsessives, with records of their gargantuan collection going back years.

Their Steam record shows Sonix unlocked this 40k badge at 9:31 am, and this matches SteamDB data down to the second. In total, Sonix owns 40,029 games on Steam. That pile o' games sits alongside 22,136 DLCs owned and 26,936 games wishlisted.

Their favorite game? According to their Steam profile, it's Alien Swarm, a free multiplayer shooter released by Valve in 2010, clocking in at 551 hours played. All those games, and their favorite is free.

The Steam Ladder reports slightly different figures, bizarrely putting Sonix at second place with 44,228 games, but the official, straight-from-Valve badge milestones don't lie. All hail Sonix, overlord of Steam sales."

Alien swarm is used for "cheating" Steam for multiplayer games ;)
Don't know why an user with 40k games is using it as it owns almost all .. :-\

I'm guessing it's used as an app/tool to allow to cheat in other multiplayer games? I'm confused too lol

That's not entirely true. I use the same technique to play Dark Souls, Prepare to Die edition. It's the only way to play online with friends. Some games with no online support, need external workarounds to work P2P, and sometimes people have to use Alien Swarm or Spacewar. It doesn't mean "cheating" or "pirated content".

It's funny that when I try to enter the games tab of a user with ~10000 games it takes a while but eventually loads, but with this one it errors out instantly. Steam knows there's no hope in loading all of that.

They're already approaching 41k, my guess is that they're aiming to also be the first to reach 50k... kinda scary to be honest, that's a backlog that can last multiple generations.

A century into the travel, two kids born and raised on board of the generational ship are talking and one of them asks the other what their hobbies are, in response they show the one asking a box full of SSD's that their great grandpa packed in before embarking on the mission "in these there's almost every video game from old Earth, most suck".

Better store them on HDD's, SSD's start to lose their data after 20 or so years of not being given any power (the memory cells basically trap a charge for each bit). Same thing for all devices that use flash memory (eventually any sealed 3DS and Switch game carts will stop working too as a result).

Please tell me my Nintendo 64 games that I have had stored away and not used in over 20 years are still okay .... PLEASE!!!!

They should be fine as long as they're stored in a non-humid environment.
N64 uses ROM mask tech which has the binary actually etched into the silicon itself. The only way it's going to lose that data is if the silicon gets damaged, breaks down, or mold grows on the rom (sometimes this is called 'bit rot'). Disc rot is way more common.

A few N64 games have batteries inside the cartridge, if you own one of those you should probably check them just to make sure they're not leaking or something.

Crazy how only 40k are profile visible games, but they're getting kinda close to 100k games apps in total (https://steam-tracker.com/ranking/apps)

You can't rely on that list to be anywhere near accurate anymore though because of this. It just hasn't updated all of the profiles yet.

I have about 2.5K games, and even if I played a new one every single day it'd take me over 7 years to try them all. This guy would probably have to play like a dozen new games a day, every day, to have even a remote chance of playing them all in his lifetime.

Everybody's got a hobby. Some make more sense than others. I suspect most of us here already have many more games in our backlog than we'll ever play, so maybe we shouldn't throw too many stones. I mean, some, but not too many.

While they are at it, they should totally buy a copy of my game, too, as it's very exclusive, only 40 copies ever sold on steam ;-0
