Hold onto your britches, Xbox 360 fans. There's a big list of games coming to Xbox One.
Microsoft will reveal the full list of Xbox 360 games playable on the Xbox One on November 9.

We already know that 100 games will be compatible, both first- and third-party. Microsoft is encouraging players to badger publishers of their favourite 360 games if they're not already announced for the Xbox One.
Microsoft's own Aaron Greenberg reckons that there's "tens of millions" of 360 fans waiting to get an Xbox One, and backwards compatibility is one of the things that going to push them to upgrade.
