I recommend that for beginners, such as myself, you add a card that shows the cost of building each structure on the screen. This could be a toggle able feature so experienced players who don’t forget if it’s 3 grain and 2 ore or 2 ore and 3 grain for a city can declutter their screen. I know that is on the “game rules” tab, but if you’re trying to play quickly, it really doesn’t help having to check. Thanks.
