Yes, you can create Roblox games using Roblox Studio tools on a PC or Mac, and then play them everywhere. You can also now permit console access for your own game and the whole Roblox Games Multiverse.
If you want to simply play your original games with friends, you can use My Games, which is found to the far right of the Games tab. Setting up My Games is fast and simple. Any game published on the Roblox website will automatically appear on your Xbox account. Any updates published online will automatically sync with your My Games place on Xbox.
From there, playing your game on Xbox with friends is just as easy to do. The owner of the place can create an Xbox party with their Xbox friends. After that, they can jump directly into the game with everyone in the party. Being social is at the core of what Roblox is all about and we hope everyone enjoys playing their own games on Xbox and sharing the experience with friends!
If you think your game is ready to be highlighted on the Featured list, send an email to email@example.com with a link to the place for our consideration. For information on guidelines regarding featured games, please see the following Roblox Wiki page: Xbox Featuring Checklist
Featured games will be displayed on the Xbox One home screen, which greatly increases click-through rates. Remember all games will be tested on Xbox and held to Microsoft Xbox requirement standards, so ensure your game and GUIs are gamepad ready!
