A Theory of Fun chpt. 4

Koster talks about games teaching people skills. I find this to be true. However, in his writing, I noticed that he seems to put together the notion that games have to teach something. This is false. A classic example of a non-teaching game, a game that takes nothing but pure luck is the common slot machine. The slot machine does not allow the player to do anything at all, yet people find it fun to play. Most people consider it to be a game. While most game teaches some skill, a game can teach no skill and still be considered a game.
