If you haven’t heard, Microsoft announced today a huge “Undo” (or CTRL-Z for Office Fans) — they have changed their Xbox One to NOT require a persistent internet connection AND now will allow gamers to trade their disc based games just like it has been.
Because of this, game sharing will not be available nor can you play disc-based games at a friends house unless you have the disc. You can sign into a friends console and play a digitally purchased game, however.
While this was hoped for, it was pretty unexpected. I think Microsoft realized they got their butts handed to them at E3. Now the field is a little more level.
