I've two ideas in my mind, but I have to think about them really well. I want to make a game that allows you to explore a weird type of map, like the brain map or the human body — something like that.
Another obligation I want to add to burst my creativity is making a game in which the drawing of the map is unusual. Maybe a card game? Or a dice mapping game? Or maybe you use an old table cloth and paint it? Something really weird.
