The game should have alcohol

I wouldn't mind it as an optonal rp thing that blurs the screen etc like in WoW.

I would not want bosses that inflict it upon characters though. It should be entirely opt in by using a flavor item for RP, not something other players or bosses can do TO your character.

There's already mechanics that revolve around mind control and forced movement, though. So it'd be in line with what exists already.
