I have added new generic question regarding Xbox One backward compatibility:
The question by itself should prove useful based on these examples (there may be more):
Can I play Battlefield Hardline online between an Xbox 360 and Xbox One?
Can I play COD: Ghosts with my Xbox 360 friends if I have an Xbox One?
Can an Xbox 360 and an Xbox One play online together with Disney Infinity 2.0?
If my friend has GTA 5 for 360 and I have one can I invite them to my game online?
Can my son play Minecraft with his XBOX 360 friends with his XBOX One?
I imagine that since this new feature has just been rolled out to everyone on the Xbox One, we could potentially get more questions along these lines.
Should we/I mark these questions as duplicates to the new generic question?
Note - this doesn't concern the recent meta regarding GTA V consolidation, as that was addressing an issue with cross-platform (i.e. PC and Playstation platforms too).
