This looks like it could be my type of RTS I hope I am not wrong...
Years and years ago my friend and I would play a game called Knights and Merchants and still do occasionally.
It was a lot like settlers in that you needed to build a house, and then train a certain person to do the job, ie a butcher to make sausages to go in the inn so that your town can eat. Each building was dependant on another and so on, with the ultimate goal being to fuel an army to wipe out the opposition.
It was grand and I loved it but I haven't really found anything similar.
Is this anything like that or is it more like AoE where you build a building and it just has a statistical improvement where you can resarch upgrades?
