"Alcohol causes inebriation, erratic behavior, unconsciousness, death"
I've always liked the idea of a 'dry' fortress, but I never really bothered pursuing the idea because I didn't like my dwarves slowing down and there was no real drawback to letting them drink. I figured dwarves simply metabolized alcohol differently than humans and therefor my human aversion to the stuff didn't apply. Now that alcohol is acting more like the drug that it is, I'd very much like to see a viable way to ween my fortress populace off of the stuff, namely by having the slowdown associated with not consuming alcohol be made temporary, and perhaps adding other physiological and psychological symptoms of withdrawal that need to be dealt with before a dwarf (or any other alcohol-dependent fortress denizen) becomes properly and permanently sober. Naturally, these problems shouldn't exist in the first place for dwarves (et al.) that are born and raised without any exposure to alcohol.
I'm not suggesting that prohibition should be easy. It certainly hasn't been in any historical sense. It could cause large amounts of tantrums and crime to deal with (is smuggling a thing in DF yet?).
A few related suggestions:
- Greater variety of non-alcoholic drinks (fruit juices/ciders, herbal teas, etc.)
- Soberness as a potential tenet of worshiping certain gods, and immigrants of related faiths entering the fortress (usually) sober
- Prohibition related crime (smuggling, speakeasys, etc.)
- Greatly reduced likelyhood of alcoholic drinks as favorites of characters born and raised sober
