Gaming platform

Hi all. First of all I am completely new to Unity3d. My question didn't seem to pertain to any other forum subject so I wanted to take my chances. I was asked to develop a gaming platform (windows 10 only) where platform will decide which games the player should play. So the gaming platform shall be able to initiate the game and the game will be sending significant actions to game server and at the end of the game, platform will display scores and may be according to scores platform will advice another game to play.
However interesting part is that platform will receive new games remotely from cloud. One other thing is that games will be windows standalone games.
Help is appreciated a lot.
Thanks in advance.
