Lego Dimensions: Starter Pack (Import)

Can you upgrade to xbox one later with a controller adapter?

Does this game require an XBox 360 hard drive? How about an active internet connection? (i.e. is additional content dowloaded?)

Is this a "Skylanders" type game? Will we continuously have to be buying more compatible figures to be able to play the game?

It says 7-14. Do you think a 5 year old could play this game?
