I'm developing a modpack loosely based around the book "The Martian". The pack will have custom recipes with Ex Nihilo/Mine Chem as the back bone of the world interaction. This will definitely be a HQM pack with the main goal to be survival. This will not be an easy modpack. In fact, my goal with this pack is to be as hard as possible. I plan to make this as realistic as possible as well so no magic mods. This also means that hunger, thirst and temperature are real problems. I'm thinking that the player will start with a lot of broken equipment and have to "repair" them with custom recipes using mod tweaker. Just wanted to get everyone's thoughts on it in case anyone had any good mod ideas that I'm not aware of.
