PVP:
Player versus Player will be a complex feature, because it will consist of many new aspects and demands intense tests and good balancing. The current combat system has to be modified in order to fit the needs of PVP as well. We plan to offer fight based PVP and economic PVP as well to come up to different preferences. PVP may include islands with luxury goods as well.
I suggest that the PvP here will be like in Spore, where you can conquer using three methods. You can use military (brute force, pretty self explanatory), or you can use economic, which through diplomatic negotiations you can buy out buildings or the other players industries, and religious power, where you would build a church, and get a priest to convert his building's, armies, ect.
