Making siege weapons buildable by military citizens on the battlefield instead of training them in a production building? Maybe both can be kept, and the on-site built siege weapons would be weaker than the ones made in a production building.
Maybe (but this is for mods with a long timespan) we could separate phase and epoch. Phase is for city size and amount/types of buildings you can build and epoch is for advanced/improved technologies and newer units etc.
Ardworix and me we already started modeling the buildings. The XML will be committed today evening, so no need to worry. It will be a faction of the Iberians. We will overwrite the public/civs/iber.json to achieve that. The hero Viriato was moved to the Lusitanian faction in the process.
thanks, updated. Units on walls was a double of Entity on Entity (prop/turret) and should rather be walkable walls. reorganized + merged redundant entries
