[quote]Do I need to buy Destiny for both Xbox 360 and Xbox One to use a single account on both platforms?[/quote]You can use the same gamertag on both platforms assuming you buy the game for both platforms [quote]If so, do I need to buy two Limited Editions (one for each platform) to enjoy in-game limited edition benefits on both platforms?[/quote]If you buy the limited edition on lets say the 360 and if you're going to play it on the xbox one presumably any skins/weapons you have for that character will also be visible on the xbox one as it's treated as the once account(I'm not sure if that applies to the season pass though) [quote] Is the Limited Edition Destiny license exclusively a physical license? Or, in other words, if I buy the limited edition, will I have to buy Destiny a second time to play Destiny without a disc in my consoles[/quote]If you buy the physical version then you will need the disc to play, however you can purchase a digital version afterwards and continue to play without the need of a disc [quote]Is there a SKU that provides both a digital license and Limited Edition content?[/quote]I think the digital guardian edition has the same content as the limited edition(sans the physical stuff) [quote] If I buy a digital Destiny license, can my wife and I both use that license to play Destiny on our shared Xbox?[/quote]It will be available to anyone who plays on your home console
