What do you think of the next Galilean Moons Space Age put 4 Gb? 3 for the basic supplies of the game being coins, supplies, goods from any era of the game (new), fp, happiness and 1 gb for a new in-game mechanics and a new mode of getting attack, defense and units in the city putting super advanced tactics (Attack and defense for the exercise of attack and defense and a random unit of your action). I put in this era being 4 gbs because we have 4 popular moons on Jupiter and it would be of great importance that it was to be divided into 4 parts being each part visiting the 4 moons of Jupiter and all of them having direct interaction with Jupiter.
A major study that could be done to put a new modality would be the gravitational forces of Jupiter interacting on its moons and even on other planets and in the asteroid belt. Would be as if at level 80 these gbs of this 10 million supplies and 10 million coins. 1 random unit per level and 6% attack and defense for attack and defense units from level 1 to 10 and 3% attack and defense at levels 11 to 80. in fp it would be 5fps from level 1 to 10 and 2 fps from 11 to 80 and 1fp from 80 onwards.
I'm choosing to have a gb of these to balance the spending we'll have in the space age where there will be in every new era an exponential increase in pfs, coins, supplies and happinesses.
In short would be 4 Great buildings targeting three gb in basic game productions (fp, happiness, coins, supplies, attack, defense, random unit (super advanced tactics) and goods from any era of the game (new)) and a gb dedicated to a new mechanics in the era.
