UPDATE TWO:

We've corrected an error we made regarding how fees can apply to accounts and different systems. Families using the same home console can use parental controls to allow multiple accounts to access the same game. The MSRP 'fees' will apply if you take a game to another console. Sorry for the confusion!

Microsoft is attempting to clarify what is quickly becoming a convoluted and confusing situation for gamers.In a blog post , Major Nelson has some good news. "Should you choose to play your game at your friend’s house, there is no fee to play that game while you are signed in to your profile," Nelson wrote. The blog post also mentioned that customers will be able to trade and sell their used games at retail outlets.However, Microsoft executive Phil Harrison, in an interview with Kotaku , has some potentially bad news. The aforementioned 'fee' to play games on a second account? Full MSRP. So if you want to play your game on another system, you'll be dishing out an extra $40, $50, $60 - unless you're logged into your main account. (Parental controls will allow you to grant access to other accounts on the same hardware.) Harrison did tell Kotaku that his company plans to allow gamers to 'trade' their used games online somehow - though declined to get into further details.IGN will update this story with more details as we hear them.Reports are claiming that Xbox One will require all games to be installed on the console's HDD before they can be played.According to Wired , if owners want to use the disc with a second account they'll be asked to pay a fee and install the game from the disc, suggesting that once games are installed you won't need to insert the disc to play.It's unclear what this means for the secondhand market, though Microsoft announced on an FAQ page (since removed) that the Xbox One is designed "to enable customers to trade in and resell games. We'll have more details to share later." It didn't reference the fees confirmed by Microsoft to Wired.We're not entirely sure what this means but have reached out to Microsoft for clarification and will update the story as soon as we hear back.
