Is it best to upgrade each building max level or spread out your upgrades? Just wonderin even tho I'll never make enough lol
The 1st level on new lands for 3tril is definitely worth it. Just upgrade whatever is cheapest for most stats.
Getting all other lands opened before going into mining,osman lands actually give better bang for the buck,personally I opened 5 mines and built on them,virtually no increase in gold per hit and only a slight increase in end plunder. These new lands are gold sinks stats only by the looks of them.
