I wonder occasionally about playing go on a graph that isn't just a square grid. It seems like hexagonal go wouldn't be too big a stretch, whereas to make a decent hexagonal chess game you have to change lots and lots of things. How about playing on a Penrose tessellation generated within some bounds, like a square or circle. Come to think of it, I wonder what Conway's Life would look like if it were shoehorned onto such a graph. I'm not sure how one would define the neighborhood, but sounds interesting to explore.
