I've been thinking about the gameplay for this game, and I started to realize that getting from one planet to another is pretty fun; but when you get to the planet, there doesn't seem to be very much to do other than science experiments. So then I was reading about the polar caps on Mars and I thought: What if there were serious dangers on the various planets? Like maybe thin ice on some planet that would break if you put too much weight on them? Or the possibility of meteorites smashing into your ship?
