Toy is interactive but a game has goals
According to Will Wright: Sim City is not game, but a toy. because it provides no objective: No victory condition, no goals.
"Toy is interactive but a game has goals"
I strongly agree Will Wright's Idea of "Toy", so I think "The Exquisite corpse" is toy and it's not game. If people don't care the result, such as The Exquisite Corpse and Scavenger hut game that we played in the class could be only toy because there was no goals of winning. (some people could do it just be cause it part of class) However I think every game could become toy that only has interaction. For example I use to play "Street Fighter II". Once I finish every characters ending; if there is no one to play with me than I feel like this game becomes "toy" I remember my self playing street fighter with no objective: just to kill some time.
