-- Creates a multiplayer game session for players. This action creates a game session record and assigns the new session to an instance in the specified fleet, which initializes a new server process to host the game session. A fleet must be in an 'ACTIVE' status before a game session can be created in it.
--
-- To create a game session, specify either a fleet ID or an alias ID and indicate the maximum number of players the game session allows. You can also provide a name and a set of properties for your game (optional). If successful, a < GameSession> object is returned containing session properties, including an IP address. By default, newly created game sessions are set to accept adding any new players to the game session. Use < UpdateGameSession> to change the creation policy.
