In your opinion, what is the base requirements to be thought of a game?
I feel like it needs to be a model of something else. AKA, the washing the dishes game is just washing the dishes. Trying to beat your previous fastest time doesn't not make it a chore in my mind.
I'm asking because I am brainstorming a game that can't be played all at once, and requires people to be doing other things, and live normal life in between. It may be a good background thing for a weekend, but is it a game?
I propose this definition of a game: something where players act within defined rules and restrictions for fun.
Thoughts?
