So for $9.99 a month Xbox One users will get access to 100 games from the Xbox One library and 360 backwards compatibility library. It's not a streaming service as far as I can tell and is coming out this Spring.
This sounds pretty cool, I don't own an Xbox One but my flatmate does and he's the sort of guy who would love this (since he only plays maybe 2/3 games and refuses to pay full price for anything). I'd be curious to see how many of these are simply single-player games vs multiplayer focussed games. They're putting Halo 5 on this, you'd wonder if they also add Gears of War and the rest of their multiplayer franchises hoping more people jump on board and start paying for microtransactions, who knows.
