Had a lot of fun making this simple Beer Pong VR Game which is entirely physics driven.
Playing demo: Beer Pong VR Game - Physics driven - Unreal Engine 4 - YouTube
Anyone interested in a tutorial?
@franktech Thanks for your open feedback! I am trying to understand what the community would be mostly interested in, whether it is basic topics or more advanced ones. This before I put time in sharing something none cares about. So +1 for the drone, -1 for Beer Pong. 
As for the game, I like your ideas, I will add them to the next version. Cheers!
