Can I play rust with the same person that game shared it with me at the same time?

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

Absolutely as long as you both have a different profiles.

Here’s everything you need to know about setting your home Xbox. Whichever consul you choose, you both need to make that one your home. Please be aware that some games, downloadable content, and access to cloud services may be restricted to the primary account holder who actually has the subscription

So the answer is no? you cannot share gamepass and be able to play at the same time somone else is? is this correct or no?

Make sure their console is set as your Home and that your account is not set to automatically sign in or that they are not signing into your account to access the games. https://support.xbox.com/en-US/help/hardware-network/console/my-home-xbox It sounds like they're accessing the games because they have your account signed in, not through the Home setting, so it's kicking you offline because you can't be signed into both at the same time and play.

What is the point of sharing if you can't play together at the same time?

Do you understand how family sharing was suppsose to work?

Do you really believe Microsoft would let you buy 1 game and play it with 2 or 3 friends at the same time?

ONLY 1 PERSON CAN PLAY AT A TIME

Are you going to wait 2 weeks for cousin Joe to finish HALO 5 so he can share it with you? With sharing you can't play at the same time. You still need 2 copies of the game to play together.

The transition to digital is happing, though it shouldn't be forced upon consumers. You can still buy all your games digitally on DAY 1!
