This text says about two types of games, first is competition games and second is collaboration games. The Author writes mainly about characters (positive side) of collaboration games. In almost parts of text has the Author tried to show the positive affections of collaboration games. But after reading I have wondering about, what is collaborating with other peoples. In collaboration games, we have to cooperate other people to defeat other group, so I think; it’s also another style of competition games.
