That leaves 1,562 Xbox 360 games that could potentially be played on Xbox One. There are currently 308 backward compatible games as of this writing meaning 19.72% of the Xbox 360 library that could be played on Xbox One is already part of the BC library. If Microsoft and third party publishers keep up this pace then it is feasible that over half of the Xbox 360 library could be made backward compatible by this time next year.
The Xbox One backwards compatibility program was initially announced during Microsofts E3 2015 press conference. The program had a soft rollout on that day and was officially launched in November of 2015.

Not to bad for about a year. Here is the guy who originally crunched the numbers:

For me, bc has been amazing. It has allowed me to buy older games with confidence since I know they are being preserved within the ecosystem. Since backwards compatibility was announced, I've played:
Beyond Good & Evil HD
Super Meat Boy
Burnout Paradise
Mass Effect
De Blob 2
Sonic & Knuckles
Monkey Island
Ducktales Remastered
Xcom
Spelunky
Tron
Dark Souls
Fall Out 3
Fable 3
Forza Horizon
And of course all the Rare Replay games
Today I'm buying Catherine and Killer is Dead for basically nothing. I hope that Microsoft continues this preservation throughout future generations. It would be incredible having thousands of games in my library dating back to the early days of Xbox 360 (or even earlier). It's even awesome just being able to screenshot/record/stream older games. How have you been enjoying backwards compatibility?
