This is nuts having only One marble quarry at once
and in fact this doesn't make any sense you can have 5 stone quarries then 3 copper mines then only 1 marble quarry at once and the amount is only 320 can we have another quarry or at least double the context like one copper mine or even have one quarry per sector
Adding the season and weather
:(It's a little boring to see the same map everytime, maybe we can add the season and weather for fun.
For example, in spring, the efficiency of reforester will be doubled. In summer, the efficiency of worker will be a little lower because of high temperature. Then, worker can drink bear or juice to recover. In that case, we can have new buildings such as fruit cutter, Juice House.
And in fall, the efficiency of farm will be doubled. Or, each fall season, the tree and fish will be re-deposited a little bit.
The weather section can be randomly, like the same as I mentioned in seasons, the efficiency can be adjusted. Besides, certain surprise could happen due to the weather, like damager from flood or work stopped for a while because of tornado.
I think it will be fun if you upgrade those awesome stuff.;)
