I would really like a kind of water system in the game, here, I'll elaborate. Water comes in various states: Filthy Mucky Dirty Clean-ish Clean Boiled Sterilised Various sources have different levels: tap water is always clean, bottled is sterilised, toilet is mucky, along with river water. There would be 2 ways to clean it: Bleach Heat Heat is pretty obvious, pot/kettle, campfire, hob, job done, boiled water. HOWEVER With bleach there is seperate stages: No bleach Heavily diluted bleach Somewhat bleachy Clean-ish Clean Dangerous V.Bleachy Powerful Barley diluted bleach This could add in complexity, for example: Joe is working for Bob, but HATES him. So, he gets a bowl of water and makes it "powerful" (enough to kil). To Bob it says sterilised, BUT, it can kill him. So? Wadaya think?
