If you used to own an Xbox 360 and currently own an Xbox One, you might have some unexpected games waiting to be discovered. As The Verge discovered, many games purchased on the Xbox 360 have recently carried over to the Xbox One and are now hiding out on players' hard drives.

Backwards compatibility is nothing new. Gamers have come to expect that their new systems will be able to play games from the previous generation—but only the previous one. This means you can play Wii games on your Wii U, but you can't play GameCube games. Saying goodbye to old games is just an accepted progression of gaming for most people, as the technological arms race between Sony, Microsoft, and Nintendo rages on. But now that Xbox has rolled out this new version of backwards compatibility, it opens up the opportunity to extend past single generations.

You can see a full list of the Xbox 360 games that are now available on the Xbox One here and enjoy reliving old games on a new console.
