You can find a lot of traffic from the Microsoft store that you will not get on the google play store or Apple store. Great for anyone using Unity 3D.

The Windows App store is an excellent marketplace for your games and apps. In this article, I will walk through the steps to publish your Unity 3D App onto the Microsoft App store.
