I got Assasins Creed with my console purchase in 2017 but now it wont launch from game list

Hi, James! Thank you for reaching out.
I'm AJ, an Independent Advisor for the Xbox Community.
I'm sorry you are experiencing issues playing Assassin's Creed.

If you don't mind, I'd like to ask you a few questions:

- May I ask which Xbox model you are using?

- To clarify, which Assassin's Creed game is this?

- Could you tell me exactly what happens when you try to launch the game? do you receive any error codes/messages?

- Are there any external devices plugged into your console? If so, may I ask where this game is installed?

Thank you! I'll be looking forward to your reply.
Best regards.

Assasins creed 3 will be the best in my opinion. but from the ones out so far i like assasins creed 2.

ill probably end up buying assasins creed out of that list.

Fall out 4 and new Vegas and I have most of the assasins creed games now as well

anybody got anything about assasins creed 4 not syncing
