I still like the idea of having the setting be some sort of desert planet. From the initial pitch we were told that the game would take place on a planet that had a stronger sun/was closer to and would thus make the effects of the sun a little more dramatic for our purposes.
From this, I kind of latched on to the idea that it should be on a desert planet, but I am willing to investigate other possibilities. (Snow and water surfaces reflect sunlight for burns as well. So planets covered in those would work good too.)
Either way, I also got a couple shots with a character who covers himself. This seems like a smart choice considering we want to avoid direct contact with light in the game.
