Didn't mean to imply that this is like a life and death issue or anything, the word pound just jumped at me when I read the event list. It really doesn't matter for gameplay purposes, but just seeing it there made me think about it and caused a reaction of major "WTF?!".
I'm not really a harcore realism advocate or anything, I can quite easily rationalize things that don't have much impact and am all fine with abstractions, but sometimes details like this just jump out at me, because I've dabbled with writing fantasy, and the amounts we're talking about here would turn any regular fantasy world upside down.
If I wanted to use an imperial measurement system weight unit for denoting amounts of gold, I'd use the ounce, that'd be 28 grams instead of 450 and change, but if IW wants to keep the pound, that's no skin off my back and won't reduce my enjoyment of the game. I'll still be going "WTF?" and shaking my head at it, but its real net effect is absolutely nil.
I just wanted to point out a humorous little detail, was all.
As for the discussion you've had, licker and PvK, I agree with practically all the points you bring up.
