Since Harmonix first announced it was bringing the Rock Band franchise to a new generation of consoles, there have been persistent questions about how the new games would support guitar and drum controllers designed for older systems. The answer to those questions comes with a price for Xbox gamers who will have to pay $20 extra if they want to use their old Xbox 360 instruments on the Xbox One. The extra cost is to cover the inclusion of a "Legacy Game Controller Adapter," which preorder listings show coming packaged with the standalone Xbox One version of the game for $80.
