Steam Machine devices officially launched yesterday, and today, Steam has launched a sale to commemorate its release.

The Steam Machine Launch Sale offers sales on a wide variety of games that are available to play on Steam Machines. Some well-known PC and console games, like Middle-earth: Shadow of Mordor, Borderlands: The Pre-Sequel, Alien: Isolation, and Dying Light, are available for sale. Some currently exclusive PC titles, like Broforce, The Stanley Parable, ARK: Survival Evolved, and Half-Life 2, are also marked down up to 80% off its original pricing.

If you purchased a Steam Machine yesterday, or plan on picking up a Steam Machine this holiday season, this would be a great time to start building up your Steam library. And then you can feel guilty every time you see your immense backlog, just like a real Steam user!

The Steam Machine Launch Sale will continue through Monday, November 16 at 10am PT.
