sunscreen for those who happen to burn faster. make the resistances to the elements random and progenerative so it's different with every character you create. or perhaps a system like project zomboid where you can gain advantages by paying with weaknesses... ex: you want to run faster and longer? you have be a hypochondriac with puny arms. You want to be able to resist heat/cold? you have melanoma and will eventually have to treat your skin. Don't limit your gaming experience, Gabe. Labels are just labels.
