So finally we define the idea.
To develop the idea, we started a brainstorm where each one suggested a freely thought , without any questioning of the other participants. It could be a reference, or a scene, or a game, or the first thing that came to mind when thinking on the subject. Then the group sit down to discuss everything we thought, without regard to our limitations.
Then reduce everything to the simplest game we could think of.
Now it’s time to start creating a game.
