GameFitNation: Creating a game inside of another game can be hard. I am not talking about mini games, I am talking about player created games. Sometimes it could be called modding, but on a console, players make up the rules and the honor system is in place to follow them. There are some games that are inherently better at creating games inside of games, these games that are good at it usually have a map editor. There is one game that embodies the ideals of the User created game, and that is Halo Horse.
