I definitely need to do something about the money, the substitute that comes with the game really is terrible. The challenge is that the spaces for it are quite small so poker chips won't really work.
I might also paint the orange cubes a different colour. Someone wasn't concentrating when they decided yellow, orange and pinky red was a good colour combination.
But neither of those are really pimping, just correcting bad production decisions. The rest of it seems perfectly good and the look of the thing is kinda gorgeous.
We've been using Victorian pennies which you can pick up pretty cheap and bulk off ebay. They're quite large though but the six pence (~20mmm) or perhaps shillings (23mm) would fit the size requirements?
