i can already answer this one shovelface,
first it's gonna be as in the first one so you can mercing, maybe there will be a radius around battles for mercs
you can work in cities to get gold, work etc or recruit troops in villages
you can offer your service to others for different tasks such as protecting a caravan, etc
you can be a merchant buying things to cities and then selling it to other cities who can't produce it for a better price
the rest depends of the community and the rp it'll bring, if someone wanna organize tournaments in a city with only the players in it straetgus will play a role, etc i let your imagination finding other ideas
PS: btw i think that trading isn't implemented yet, so don't expect this part in the first release
