600 diamonds for a single Zeppelin is just rediculus
It's even more rediculus that the Zeppelin costs 100 diamonds more than the Natural History museum, but still the Zeppelin provides 500
less happiness.
The blueprint cost (200 diamonds) is ok, but please lower the costs for buildings. And please don't raise the premium buildings costs for each age. I mean, 2 eras further and what, will a single cultural building cost 800 diamonds? Also, please base the diamond cost depending on the buildings size.
Come up with a base cost for cultural buildings. In this example, lets say 300 diamonds. The base size is 4x4 squares. Bronze Age gets -50% cost and Iron Age gets -25% cost.
Examples:
Theater
Cost: 0.5
Squares: 4x3 = 12
Modifier: 12 / 16 = 0.75
Diamonds: 300 x 0.5 = 150 x 0.75 = 113 diamonds
Amfitheater
Cost: 0.75
Squares: 4x4 = 16
Modifier: 16 / 16 = 1
Diamonds: 300 x 0.75 = 225 x 1 = 225 diamonds
Pillory
Cost: 1
Squares: 2x2 = 4
Modifier: 4 / 16 = 0.25
Diamonds: 300 x 1 = 300 x 0.25 = 75 diamonds
Printer
Cost: 1
Squares: 3x3 = 9
Modifier: 9 / 16 = 0.5625
Diamonds: 300 x 1 = 300 x 0.5625 = 169 diamonds
Palace
Cost: 1
Squares: 4x4 = 16
Modifier: 16 / 16 = 1
Diamonds: 300 x 1 = 300 x 1 = 300 diamonds
Travelling Circus
Cost: 1
Squares: 5x5 = 25
Modifier: 25 / 16 = 1.5625
Diamonds: 300 x 1 = 300 x 1.5625 = 469 diamonds
Natural History Museum
Cost: 1
Squares: 6x4 = 24
Modifier: 24 / 16 = 1.5
Diamonds: 300 x 1 = 300 x 1.5 = 450 diamonds
Zeppelin
Cost: 1
Squares: 3x6 = 18
Modifier: 18 / 16 = 1.125
Diamonds: 300 x 1 = 300 x 1.125 = 338 diamonds
A similiar system could be used for premium production buildings aswell
