1). Iron swords- Is not good to produce iron swords in your building. Look in your buildings.
Your builing take you 4 iron ore to make only 1 iron. Than you need 2 iron to make 1 iron swords.
This mean you need 8 iron ore for only 1 iron swords and this is very bad.
You need to sell iron ore in TO (trade) for price: 3 iron ore for 1 iron swords.
This mean 3.000 iron ore for 1.000 iron swords. This is best for new players.
Not only you get more swords but you save your coal too. Strong players have better buff and grow production so dont vory, people will buy your offer.
2.) Steel swords- same things is like steel swords, if you look on your buildings you will need to much iron ore and coal too.
In TO (trade) you can sell 4-5 iron ore for 1 steel swords. I sell to many time 4k but 5k go very faster and easy.
3). Gold coins- If you try to produce gold coins for 2 gold ore you get 1 gold bar in you building and for 4 gold bar you get only 1 gold coins from your building.
This is very bad and this mean you need 8 gold ore for only 1 gc. You lost more marble and planks than you get gc.
Marble and planks value more than you get gold coins.
Better if you sell in TO (trade) 1k gold ore you get 400 gold coins or even more.
This is lot better than you produce gold coins. This is only for old players who have strong buff and buildings in big lvl-s.
