I don't mind the aesthetics of this current UI, but I just cannot fathom why they hid how many hammers a building costs, how many beakers a tech costs, how many happiness a celebration costs, etc.
How can I make intelligent choices if you don't give me all the relevant information?
Similarly last night I was at war with Greece and went to hover over their unique unit. The game would not tell me it's strength, whether it had taken any damage yet, or whether it had any terrain bonuses.
I just can't wrap my head around not including things that are fundamental to playing the game. Again, this is entirely sidestepping any question of aesthetics
