You might have a game in your Steam library that has caused such visceral disdain, you’ve wanted to completely and utterly wipe its existence in your mind forever. Up to now, you were only able to delete the local files but still have the hollow reminder of the game that once was in your library. The only way to do away with that ghost was to lock it into a hidden category and never look at it again. Well never fear, you actually have the option to completely and permanently delete the game from your library.
All you have to do is go to the Steam support page, login, go to the ‘Games, Software, etc.’ tab then look for the game you want to delete. Upon going to the game, you’ll clearly see the the option ‘I want to permanently remove this game from my account’. Upon doing so you’ll have one last chance. But if you’re at this stage and you’re not just looking, it’s obvious what you want.
Now, on a serious note, it’s hard to think of a game that truly warrants this level of annihilation. Hide it into obscurity, delete the local files or refund the game. There are so many other options to deal with a game you don’t have much love for. That said, the option is nice and should there ever be a specific need for this feature, then it’s totally justified. For now, I just don’t see the appeal.
