Purchased my son an Xbox One for Christmas, along with Far Cry 4 and CoD Ghosts (having seen the game deals on here). Console came with Assassins Creed Unity & Black Flag. However, he has lots of games for his 360 (he will still use the 360 once I've worked out how to connect both consoles to one TV and switch them over easily when he wants to change the console he wants plays on).
Anyway, I have purchased the cheaper Minecraft upgrade via the Xbox Store but don't know if I am able to do similar with other games (specifically GTAV and FIFA 15 - Ultimate Team Edition).
Any advice from the gaming community would be appreciated as I don't really know what I'm talking about (you can probably tell)!
