We got a Day One and it's in my sons' room, figured I'd move it back and forth as necessary. That's just not going to work out as well as I'd like so I'm going to buy a second Xbox One within the next few days. My XBL account is gold and on the Day One so the boys should have online gaming access with their silver accounts, no problem, without my having to be signed in on the Day One. I'm going to download my XBL account to the new Xbox One, probably put their silver accounts on there as well. Again, not a problem, as each account will only be signed in on one Xbox One at a time. But how's it going to work for XBLA games and DLC? I'm figuring I should buy and first download all digital content on the Day One under my account so that should give the boys use of it without me having to be signed in on the Day One. Then redownload the XBLA games and DLC I want to use on the new Xbox One. I'll have to be signed in on the second console to use the digital content, but, again, I don't have to also be signed in on my sons' Day One, the original download console, for them to use the content -- still only a single sign in required for my account. (Obviously we probably can't be playing the same digital games and/or DLC on both consoles at the same time, but that's not a problem, either.)
Does this make sense per XBL digital content policy? I don't mind buying the second Xbox One but I don't want to have to buy two copies of the same games and DLC for the same household. They don't have to be played on both consoles at the same time but I don't want to have to buy them twice to be played at all on both consoles.
