hex have six directions with uniform distance, square has four. diagnals are an eternal meme.
Not true, hexagons distort diagnal moves as well. AND have 2 less directions you cant move in. Loose loose.
also was reading some signal papers that hex gates generally work better than square for similar reasons bees use them; they just have a mathematically better fit with space.
I suppose it depends exactly what you mean by that. Space packing is the same of course… so not sure what “better fit” means exactly but id be curious to find out.
