I purchased my first Xbox Play Anywhere game last week - Forza Horizon 3. I installed it on the Xbox and Windows 10. Pretty cool all the saves are shared and you can play on either system. I will say the game is smoother on Xbox but on medium settings it's pretty good on Windows 10. I really like the idea of play anywhere because the xbox is on the main tv and it's often times being used by Michelle so I can just play in my office. I tried the streaming feature directly from the Xbox to my Surface Tablet and it played ok but there was a bit of lag.
