If you don't like the idea of your library being filled up with hundreds and hundreds of titles you know you'll never play, why not clear out the backlog and remove them from your account permanently? Sure, it's not an option for everyone -- I wouldn't do it -- but it's a feature that's now supported by Steam.
A NeoGAF user spotted the change earlier this morning, which can only be accessed by going through Steam's support pages.
To permanently remove a game from the Steam application, simply click Help and then "Steam Support" in the drop-down menu. From there all you have to do is pick "Games, Software, etc." at which point you'll be able select one of your recent products or search for any games or software.
Once you've selected a game that's in your library, Steam will then ask you what the problem is, at which point you'll see an option to "permanently remove this game from my account".
BEGONE, I say
Users have noted that games added as part of a package can't be removed individually, which is important if you've ever purchased something through Humble Bundle or bought some of the larger packages available on Steam.
What's the merit in all of this? It's really only for spring cleaning. Most people will just hide games from their Steam account or create a separate tag to categorise all the trash in their library. But, for some, there are those impulse purchases and special titles that just have to be purged with fire. We all have one or two of those.
It's also worth noting that the functionality has been available for a while when it came to free-to-play games, but it's only recently been rolled out for paid titles. And if you have a few that you never want to scroll past ever again -- well, now you don't have to.
Still a little over the top for my liking, but hey, the more tools the better.
