Sorry, this is probably pretty obvious to everyone else. I am buying Flight and addons for my grandson as he enjoys mine so much. Will he be able to use Flight both at my house and his own simply by logging in using his own account. Many thanks in advance for any answers.

Yes he can log in with hes own account, the game will then restart and will load the addons purchased with that account.

But it will not load his progress in the game! Happened to my boy.This is a crucial point IMO, and one MS needs to fix if GFW is to be really taken seriously..All of your achievments and awards etc are stored in your GFW account, but any of your completed missions and challenges are not. Please fix MS!!You can copy across a folder from one PC to the other if you are that way inclined.The path is C:UsersUsernameAppDataLocalMicrosoftFlightPlayersfunny number here Copy the funny number folder that is his profile. You can tell by the access date as to who's is who's. Copy to the same location on the other PC and you're set to gobestjake

Thanks OHN and Jake. Very useful to know

Just as the guys above said.At the moment, all DLC is tied to a single gamertag, so he can download the DLC and play Flight on as many PC's as he wants.Jake; made a very good point.
