Gold related buildings not worth building!
A note to all those that play for free: It is not worth building the gold related buildings. Unless you are paying real money to purchase the golden parrot to continuously resupply your mine, the cost of resources to rebuild a gold mine is far greater than the gold you will produce. (Even if you buff!)
Here's the math:
A gold mine produces 300 gold ore.
A gold smelter converts that 300 gold ore into 150 gold bars.
The coinage converts the 150 gold bars into 37(.5) coins.
Now, what resources do you pay to get those 37 coins?
1200 coal (in the smelter)
1400 hardwood planks (for the mine)
1400 marble (for the mine)
1500 tools (for the mine)
With the going rates in the open trading market, I can easily sell 400 marble for 25 gold coins. So, if I just sell 800 marble instead of going to the trouble and time of making coins, I'm already ahead 13 coins. Now, if I traded all the resources I listed above, I could easily get 300+ coins, almost 10 times the cost of producing gold!!!!
Of course, this math only works because gold is traded far too cheaply on the open market. If prices adjusted to the true worth of gold production, people would be paying 2 coins for 400 marble, 4 coins for 400 beer, 5 coins for 400 bronze swords, etc. And, as most of you know, commodities with prices like that get snapped off the trade market in a heartbeat.
So, until the price of gold coins adjusts, I will just leave the smelting to someone else!
Anyone with an economics degree want to comment? :)
