whats windows metro?? is video ads available for windows 8.0 pc users now?

I CANNOT UNDERSTANT WHAT IS MEANT BY WINDOWS METRO , I AM CONCERNED ABOUT WINDOWS PC 8.0 USERS ARE THEY GETTING THE BELOW RECOMMENDED FEATURES OR NOT?

"Windows (Metro and Windows Phone 8.1 only):

  • Windows users can now receive custom in-game messages such as event activations. Note: Windows Phone 8.0 users are excluded from this.
  • Video ads are now available for Windows Phone users. Note: Windows Phone 8.0 users are unable to watch video ads.
  • Windows users can now login with Facebook and take advantage of the features introduced in v2.1. Note: Windows Phone 8.0 users do not have the option to login with Facebook, which means that you’re unable to get the Insta-Troop slot related to that."
