Ok so this is complicated. FIFA 20

Try make a Soft Reset on your Home Xbox, and remake the configuration of your Profile in Xbox to see if works

unfortunatly only one gamertag can be linked to an email at a time

simply create a new free email account for your grandson to create a gamertag that you will be able to associate it to.

(you will also be able to set it as a child account and apply parrental control settings to it)

this will also prevent you 5 year old grandson to have access to you private emails

since your email and password is required to log in to xbox live you would be giving your grandson access to all your microsoft services (including access to your billing info)

for security reasons (including the one's i just mention) microsoft preffer that everyone use sepperate accounts and not to share your info with anyone

you can create a new account here: https://signup.live.com

Ok, this is very wired, Because i am a big lover a FIFA i like to play FIFA 11 quite alot, but, when i put the disc in i can load it and i can play it for 10-20 mins max then it dissconnectes me,but yesturday i thought well i'll try 2 games "Halo Reach,
MOH" and they worked perfect no discconects nothin, so whats happening???

Volta Mode is really funny but only the gameplay.. the Story is too excessive or too mainstream.. and I like only the gameplay on big fields.

On the small fields too mich random goals because of rebounds.

Other cons:

No volta available playing online versus friends.

No volta available to playing with real clubs or national teams.

career mode is boring again.

Fut not tested yet.

I didn't bought but I'm hearing a lot of good stuff, I'm thinking of download the demo.
