It really takes soooooo long before I can build a ship!
Most mines are at level 13 or 14. The shipyard is high enough already with level 13. The explorer skills are at 12, so 8 more levels to go, guess I will take at least 2 more weeks before I can start to explore!
Guess I will now focus more on explorer/shipyard skills too. Atm I'm only upgrading it when I lack resources upgrading my production mines. XD And yep it really takes sooooo long every upgrade, hope this will pay off in the future xD
