Here's how Xbox One backward compatibility works
The Xbox 360 had a dedicated spot in millions of living rooms, bedrooms and offices for nearly 10 years, and during that time, players purchased massive libraries of games. However, when the Xbox One launched in 2013, it didn't include the ability to play or transfer Xbox 360 games, a disappointment for many fans. That's why Microsoft's announcement at its E3 showcase was so exciting: The Xbox One is getting backward compatibility this holiday, with a lineup of more than 100 fan-requested Xbox 360 games to start and more to be added as demand warrants. Xbox One backward compatibility runs an Xbox 360 emulator right on the console, which is no easy feat, Microsoft General Manager of Games Publishing Shannon Loftis explains during a chat at E3.
