If you have a Steam account, you’ve probably done it at least once: bought a game you either instantly or later regret buying. Not because of the money spent, but merely because it appears in your Steam library. Whether you just know you’re not going to play a game ever again (or maybe you’re trying to break an addiction), or Putt-Putt goes to the Moon didn’t turn out to be as exciting as you remember it, or maybe you get weird looks for that copy of Showering with your Dad Simulator, you no longer have to stare at that unwanted game, and you don’t have to hide it, either.
Here’s how to completely, permanently remove the game from your library, via NeoGAF. Keep in mind this is irreversible and would require re-buying the game.
First, you’ll log into Steam’s official Help site.
There’s a search box at the bottom of the page in which you’ll type the title of the game you’re looking to remove. Punch it in there, and click on the game when it comes up. Select “I want to permanently remove this game from my account” as the help option you’re looking for.
From there, you’ll be warned about the ramifications of the change, and and you can click OK from there. The game’s gone permanently. If the game is part of a bundle, or has associated DLC, those will also be included and removed as well, and you’ll be warned of that, too.
It’s complicated enough that you won’t do it accidentally, but easy enough to do when clean-up time comes around. Time to dive in and start emptying out old demos.
