A quick tally of my personal Steam library reveals an extremely average value of a few thousand bucks. That’s around the 50th percentile of all users on Steam after roughly 15 years of PC gaming. Nothing to write home about.

But what about the most supreme Steam user? As spotted by PC Gamer using the powers of Steam Ladder’s user data, the most expensive Steam profile on the planet clocks in at $279,114.

That’s not just the value of their Steam games, though those are still fairly substantial at $35,995.31. This ultimate Steam profile, which goes by the name St4ck, has $242,881.69 worth of cards, badges, animated player images, and everything else that most Steam users ignore whenever there’s a big sale going on.

Since most of us PC players tend to ignore cards and/or sell them as soon as they’re acquired via gameplay, Steam provides users with digital trading cards for playing games but also for taking part in Steam events–usually big sales like the most recent Open-world Sale. Gather the full set of cards available for a game or Steam items from a sale and you’ll earn a badge that’s not only highly valuable in terms of dollars and cents, but also in terms of Steam XP.

St4ck has a lot of them. In fact, St4ck has 6,500 badges along with 566 foil badges, making them the biggest owner of cards and badges in the world.

St4ck is also in the top 0.1% of game owners in the world, although they spend most of their time playing CS:GO, H1Z1: King of the Hill, APB Reloaded, and The Elder Scrolls Online.

We don’t know much about St4ck, but we do know they had a Twitter account with images of what might be a pet chimpanzee and a personalized 2017 Steam Summer Sale badge. According to YouTuber McSkillet, St4ck is a member of the Qatar royal family, which explains how they can spend $30,000 on PC games and still spend half of their time playing Counter-Strike.
