Here's why you can't play directly on the Xbox 360 Arcade:
* It's not a separate platform: The Xbox 360 Arcade is just a specific version of the Xbox 360 console. It runs the same games and software as other Xbox 360 models.
* Games are played on the console itself: You don't play games directly on the Arcade, but rather on the Xbox 360 console that you own.
To play games on an Xbox 360 Arcade, you need to:
1. Have an Xbox 360 Arcade console: This is the physical device.
2. Purchase Xbox 360 games: You can buy them physically in stores or digitally from the Xbox Live Marketplace.
3. Insert the game disc into the console: If you bought a physical game.
4. Download the game: If you bought a digital game.
Then, you can launch the game and play it on your Xbox 360 Arcade console.
