Can a Xbox arcade play downloaded games?

The Xbox Arcade is a service, not a console. It was the name of a service offered by Microsoft on the original Xbox console, which allowed users to download and play games.

However, the Xbox Arcade service is no longer active. The original Xbox console is considered outdated and no longer receives software updates. Therefore, you cannot download or play games through the Xbox Arcade on that console.

If you're looking to play games on an Xbox, you'll need a modern console such as the Xbox 360, Xbox One, or Xbox Series X|S. These consoles allow you to download and play games from the Microsoft Store.
