I love how Microsoft have put so much effort into BC and it's one of the best features so far this gen and it also primes them going forward as X1 catalogue will be fully available on the Next Box which is also great as if they get their image right going into the next gen there are some very nice games people who skipped on Xbox this gen can pick up and play.
Whilst you hear a lot of people dismissing the value of BC or saying that they don't care about old games it's a very valuable part of the Xbox One for me as when I look back their is so many games that I have missed out on that I wouldn't get the chance to play otherwise, My taste in gaming now is vastly different to what it was 12 years ago when the Xbox 360 launched and I have realised on how much stuff I missed out on playing through the 360 gen that is now possible to play on the X1.
Whether it's old favourites I can revisit and enjoy once again and not only that they have greatly improved performance and with the X improved graphical quality and then you come along to the 360 games that have been patched for the X and have 9x the resolution which is 720p >4k, sub 720p games just fall short as it's a straight up 9x increase and getting to play games like Fallout 3 (12:30 in the video shows the difference) will be such a pleasure.
Then there are the games that I never had any interest in as they released due to my tastes in gaming back then or those that went by without me knowing about them and discovered them years after which without BC I probably would never get around to playing at all.
