If you missed the sessions presented by Microsoft MVPs at the 2015 Microsoft MVP Virtual Conference, you should check them out on Channel 9.
I was given the opportunity to speak here and decided to give a talk on creating a global leaderboard in Azure, using Azure Mobile Apps (or Azure Mobile Services). The client that was using the leaderboard information was Unity 3D. I also used Postman REST Client quite extensively during the presentation.

If game development interests you, make sure to check out another webinar I did where I created a 3D game in 90 minutes using Unity 3D!
