I'm a bit of a noob when it comes to all things XB so I was hoping the XB veterans can help me out. I've got my son a XB1s for xmas with a little pile of games I've been collecting for a while. I'd like to surprise him with it XMAS day and not have to worry about downloading games etc.. Whats the best way to do this so he doesnt find out? He's already got a 360 and an XBL account (not gold). I don't want any notifications or anything showing up on his account. Ideally I'd like to install all the games FH3 / Halo / Forza 6 so he's just got to sign in with his XBL account and crack on. Thanks!
