In Ships of Battle:Age of Pirates from Artik Games the factions have missions like protect this ship and help her reach tortuga or bring wood etc since S&B has more budget and it isn't a mobile game it could have more missions and harder missions like if you join Portugal after some missions you could have this type of missions.
"Since the treaty of Tordesilhas is no longer active his higness the King orded the colonization of the land of Australia go there and help colonize" after missions of helping establishing a Portuguese Australia we could have another like this.
"The effortes of colonizing australia were a complete sucesse his higness want to colonize the land of New Zealend you know what to do".
After helping we could recibe rewards like portuguese clothes flags etc.
We could also like in the Age of Pirates attack enemy ships defend forts and attack enemy forts and if we helped a faction we would be friends we that faction and be enemys of rival factions.
What do you tink?
