I never even drink alcohol in games. in fallout, I only ever use stimpaks. unless I'm desperate for healing. and in skyrim I rarely use healing potions unless I'm in the middle of getting killed, then I'll use them
but what's the point? I guess, in games where it already exists, it could be a fun little thing. but I don't think it's really a big enough deal to complain about it in games where it isn't done "right"
