There are maps with very little gold mines or stone.
It’s the case right now for flankwood and crater. (Because the meteorite don’t give silver).
If the devs think an extra silver on top of gold is too much, there should AT LEAST be an option to toggle between gold and silver when trading. At minimum. Because otherwise on some maps its impossible to get all upgrades even after 1h and the two imperials landmarks become useless.
I also think meteorite should give silver, as other civs are not losing their bonus on that map.. (French isn’t losing faster vills production just because they decide to mine meteorite instead of normal gold, china/zhuxi can supervise it). If you go for meteorite you cannot get upgrades in early feudal which feels very wrong. While the opponent can get their eco bonus, get their extra stone AND get upgrades.
