I'd be interested to know their plans for sizing bourbon barrels assuming they go the route of alcohol in the game. A part of me subscribes to the thought that your whiskey barrel need simply adhere to the ASB™ (American Standard Barrel). But then we're talking about a fantasy setting so how will they justify the dimensions based upon a real life country's standard? Sure you could go Butt, Quarter Cask or Standard Hogshead (nice fantasy ring to it I might add!) but then that begs the question are you settling for smaller in game aesthetics. Jeebs I need a drink to process this.
