According to the docs here:
https://api.playfab.com/documentation/matchmaker/method/StartGame
It seems this call will either return a successful response, or InvalidParams, or BuildNotFound.
But what if there are no available game servers?
Will there be a response such as "NotEnoughGameServers"? If not, any recommendations on how to fail gracefully? (e.g. I want to log useful error messages and ideally tell the client what is going on. Later, I'd like to implement a queue where people can wait until a game server is available)
