Guys the annoying part of this game is that there is not enough guidance to know what and how to do, in order to make ships I need cannons, I got warmachines, but do not know how to get cannons out of it, as most of the western civilization choices are closed? So do inform Please, as I know you are caring and good advisors
The only way I have found to get them is by getting 840 nobleman in the city. That will unlock the cannon foundry under the nobleman building set
