If you don't have a game you want to play yet, there are two ways to get one. First, you can acquire a physical copy of the game. This can be either a new copy or a used copy, so you may be able to find a good deal on a website like eBay or Amazon (or at your local video game shop).

Used copies work well because the Xbox One doesn't actually play the game from the disc. The Xbox One just needs to check the disc and verify what it is. The actual game is downloaded from Microsoft's servers and run from your Xbox One's hard drive. As long as the Xbox One can recognize the disc, you're fine.

Once you have the disc, insert it into your Xbox One. The Xbox One will tell you it needs to download an "update" for the game. It's really downloading the entire ported version of the game.

When it's done, you just have to launch the game like you would any other. The Xbox One will need the game's disc in its disc drive while you play it to confirm you do indeed own the game, but the game will actually run from the Xbox One's internal drive and not the disc.

You can also purchase digital copies of Xbox 360 games from Microsoft's Xbox store. If you already own a digital copy of the game, you'll find it available for installation on your Xbox One alongside any normal Xbox One games you have. Head to My Games and Apps > Ready to Install to see games and apps you can install.

If you have an Xbox Live Gold subscription, you'll also be able to download the Xbox 360 games given away for free every month on your Xbox One. Microsoft has promised that all future Xbox 360 games included with Xbox Live Gold will be compatible with the Xbox One.

The main products include game controllers and accessories compatible with PlayStation, Nintendo, Microsoft, Android & iOS, PC and other game platforms.

Downloadable content works in backwards compatible Xbox 360 games on the Xbox One, too. You can buy the DLC on the Xbox Store and it will "just work" in the backwards compatible game, as if you were playing the game on an Xbox 360.

Games with bundled DLC should work properly. For example, Red Dead Redemption for Xbox 360 is available in three different editions: Red Dead Redemption (standard), Red Dead Redemption: Undead Nightmare, and Red Dead Redemption: Game of the Year Edition. All three discs are compatible and work how you'd expect them to. The "Game of the Year" edition disc comes with all the additional content, so it will just work in the game. The standard disc doesn't come with any additional content, but you can choose to purchase the DLC from the Xbox Store and it will be enabled in your game.

That's how it should work for most games, in theory. In practice, we found that the Xbox One just downloaded the base version of Fable II when we inserted a Fable II: Game of the Year Edition disc. The system wanted us to purchase the DLC that should have been included with the game. The Xbox One can't seem to tell the difference between the base and game of the year versions of this particular game. The Xbox One may be confused about some other "Game of the Year" games and their DLC, too--we're not sure if this problem is specific to this one game or not.

All in all, though, the system works pretty well--and should have you playing your old Xbox 360 games in no time.
