Fans of backward compatibility are getting their wish: Microsoft just announced that the Xbox One will be able to play Xbox 360 games. Demonstrated onstage with Mass Effect by Mike Ybarra, it sounds a lot like the OG Xbox -> Xbox 360 setup -- you just plug in the disc or download the game, and the system plays it, but now with Xbox One features like taking screenshots, Game DVR and game streaming included. All developers need to do is approve a game for backward compatibility for it to work, so the list of compatible titles could grow rapidly.
Update: Microsoft updated its website with more information about the new program. The page confirms that this applies to digital and disc games, cross-console multiplayer is included, and it will pull over your cloud game saves, achievements, Gamerscore etc. This PDF lists all the games it currently works with -- excuse me while I dig up my Perfect Dark Zero Collectors Edition.

Microsoft took a chance to ding Sony for its PlayStation Now streaming setup too, promising, "Gamers won't have to pay to play games they already own." If you're in the Xbox preview program, you will be able to try this out later today with a limited set of titles. A teaser image for the feature showed off other games like Perfect Dark Zero, Gears of War, Super Meat Boy, Halo Reach, Halo 3, Shadowrun and Borderlands. We'll try it out once it launches, but wow, funny to see this here just two years after Don Mattrick called it "backwards."
