I want to buy an Xbox one X

That will entirely depend on the bundle you're getting. Unless it explicitly states that it comes with a code for a game (Example being mine that came with Fallout 76), it will not come with a game. Here's an

example of how the box will look when you're buying an Xbox One X that comes with a game included.

I have Xbox one x, want to buy GTA v for Xbox one x|s for $39.99

When hovering over the buy button in Microsoft store on GTA v series x|s a small text bar appears saying. This is not playable on this device.

I have Xbox one x.

But the store says GTA v series x|s is not playable on my Xbox one x.

Its on Xbox Series X/S, Xbox One, and I think Xbox 360

If you want to play you'll have to buy it.

I'm very excited!!! Like the previous post, I got Day One Xbox One S 2TB. I will not get rid of it! I want to buy Xbox One X, wanting to preorder already from Microsoft or another realiable "third party." But want to know if Xbox One X supports external
hard drives like the S. I probraly not paying attention to news.

Perfect thanks. I want to buy Xbox serie X and i have a Xbox one. My doubt was if both was the same. Solved. Thanks
