While I enjoy the grid system used within the game, I think that it could be improved if you could build at angles other than 90 degrees, even it was just 45. The octagonal walls included within the game are nice, but they are too short to make a large octagonal building, something I am a fan of. I realize that this would be possible by creating multiple buildings, but that is far more time consuming than if the grid allowed for diagonal walls. I hope I am not alone in this request.
