The first batch of original Xbox games will soon be playable on the Xbox One. 13 games will be available for you to play from tomorrow onward. 

Microsoft has already made the Xbox One backwards compatible with hundreds of Xbox 360 video games. Now it's the original Xbox's turn. The first 13 video games have been revealed down below. 

• Star Wars: Knights of the Old Republic
• Ninja Gaiden Black
• Crimson Skies: High Road to Revenge
• Fuzion Frenzy
• Prince of Persia: The Sands of Time
• Psychonauts
• Dead to Rights
• Black
• Grabbed by the Ghoulies
• Sid Meier’s Pirates!
• Red Faction II
• BloodRayne 2
• The King of Fighters Neowave

Not only will the games be playable on Xbox One, but the newer console increases the visual fidelity. Some of the games will look much better on the Xbox One than they did previously on the original console. 

If you own the original discs, you can pop them inside the Xbox One and they should be playable. Alternatively, you can also purchase/download original Xbox games via the digital Microsoft Store.
