Umm, this sounds pretty amazing to me.
This right here is how I will let people borrow my games, only it sounds to me like I'll also be able to play my own games at the same exact time as up to 10 of my friends and family are. This is fucking amazing, if true. Microsoft needs to be asked about this for clarification pronto!!!
My biggest concern about used games (which I don't buy) was being able to let friends or family borrow and play my games, and it sounds like that's completely addressed with this system. I'm a happy camper. There is only a restriction if you plan on giving someone your physical game disc. They have to be on your friends list for at least 30 days, and each game disc can only be given once. Microsoft also needs to be asked about this specific part here. Are they saying that they original giver of the game disc can not receive the game disc back from the friend they gave it to? Or are they saying that the original owner can only ever give their physical game disc to one person ever, but that the original giver of the game disc should also be able to receive that game disc back and have it work with no issues?
