New types of metals copper, gold , bronze , granite , etc. More better ;)
[Europe 1]He who fights with monsters should look to it that he himself does not become a monster. When you gaze long into the abyss, the abyss also gazes into you.
But we would need mines for them, finding copper or gold would be bad.
Bronze is mined or created by humans?
Granite, lime etc but in stone quarry. And spots for quarry should give finite amount of resources. After they are depleted "quarry spot" is spawning in different part of map, so one group wouldn't be able to have every type of resources forever... they would be forced to trade.
bronze is combination of tin and copper. so u shouldn't be able to mine it.
