Reserves open slots in a game session for a group of players. New player sessions can be created in any game
session with an open slot that is in <code>ACTIVE</code> status and has a player creation policy of
<code>ACCEPT_ALL</code>. To add a single player to a game session, use <a
href="https://docs.aws.amazon.com/gamelift/latest/apireference/API_CreatePlayerSession.html"
>CreatePlayerSession</a>
</p>
<p>
To create player sessions, specify a game session ID and a list of player IDs. Optionally, provide a set of
player data for each player ID.
</p>
<p>
If successful, a slot is reserved in the game session for each player, and new <code>PlayerSession</code> objects
are returned with player session IDs. Each player references their player session ID when sending a connection
request to the game session, and the game server can use it to validate the player reservation with the Amazon
GameLift service. Player sessions cannot be updated.
</p>
<p>
The maximum number of players per game session is 200. It is not adjustable.
