This object represents a game. Use `BotFather <https://t.me/BotFather>`_ to create and edit
games, their short names will act as unique identifiers.
Objects of this class are comparable in terms of equality. Two objects of this class are
considered equal, if their :attr:`title`, :attr:`description` and :attr:`photo` are equal.

title (:obj:`str`): Title of the game.
description (:obj:`str`): Description of the game.
photo (List[:class:`telegram.PhotoSize`]): Photo that will be displayed in the game message
in chats.
text (:obj:`str`, optional): Brief description of the game or high scores included in the
game message. Can be automatically edited to include current high scores for the game
when the bot calls :meth:`telegram.Bot.set_game_score`, or manually edited
using :meth:`telegram.Bot.edit_message_text`.
