I love this game and there is not much I would change about it, but I think it would be good to have more variety of scenery and tunnels on the moon, just like with the crazy pieces, once we have used it in campaign mode, it would be great if they became available to us on our sandbox. I just feel that with the same scenery all the time, I feel like I'm building the same sort of roller coaster all the time and it would be exciting to have more variety.
