You know why this is interesting? You know why everyone on this site should be at least paying attention? Because I think it's the first potential Operating System to be built with the purpose of playing video games at it's core... Windows runs games great and I adore it because it's the easiest place right now to play all of the video games ever pretty much... but Windows is legacy, it's old as fuck and the fact that it runs games is almost a happenstance, barring any surprise interest shown from Microsoft once the Xbox One era for them gets going I highly doubt they will be pushing gaming on Windows any harder than they have already, there's been almost zero effort publicly put forth from them for gaming on computers and even the way the 360 controller has found new life on the PC has way more to do with Valve and Steam pushing it's integration in an official way than anything else, it's lucky and it's sad for Microsoft.
So why should you care about an operating system purportedly built for games? How could you NOT care... your on giantbomb dot com I assume you like video games, maybe even love them, so start showing your love for games and the possibilities for even better games under a possible new platform that could help make them better for you! :)
