Defining the word ‘game’ is tricky. There’s many kind of different ways to define a game. We all know that Diablo is a game, and a painting of Mona Lisa isn’t.
Or is it so?
But what if nobody plays Diablo? Is it a game anymore? How could it be a game, if there was absolutely nobody playing it? A game requires a player.
And what if somebody makes a game out of painting (he watches the top edge, closes his eyes, turns his head a bit and tries to make so that his eyes will see bottom edge when he opens his eyes again).
Wouldn’t this suggest that Diablo as-is, actually isn’t a game. It becomes game only when somebody plays it.
And wouldn’t this suggest that anyone can play a painting if they want. It becomes a game if somebody plays it.
