 * Room games
 * Pokemon Showdown - http://pokemonshowdown.com/
 *
 * Room games are an abstract representation of an activity that a room
 * can be focused on, such as a battle, tournament, or chat game like
 * Hangman. Rooms are limited to one roomgame at a time.
 *
 * Room games can keep track of designated players. If a user is a player,
 * they will not be allowed to change name until their games are complete.
 *
 * The player system is optional: Some games, like Hangman, don't designate
 * players and just allow any user in the room to play.
