Xbox UK marketing director Harvey Eagle would probably be freaking out given the reaction to the recently revealed Xbox One. Some of the outrage that’s bee going around has to do with the console charging a fee for used games. Some sources even state that it will block used games entirely.
However, speaking to GamesIndustry International, Eagle stated that, “We are building the Xbox One to support the trading and re-selling of used games. We are working through the policies of how that will work right now, but we will not block used games.”
So it seems you will be paying a fee to install games on another Xbox One console (since it will be coded to the original system it was used on, making it “used” for other consoles).
Regarding the rumours of the Xbox One being always online to function, Eagle stated, “The answer to that question is no, you do not require an always on connection to use Xbox One.”
