I suggest you check this one out:
Its faction based, yet you can just create your own faction. Territory control, cities and villages, naval warfare, not to mention politics are in. FFA PvP after x levels (Newb protection). Uses cryengine 3, and looks awesome yet doesn't require much from your PC (apart from masssive RAM consumption of 2+ gb in capital cities), not to mention the psychics allow you to cut down trees (they actually fall to the ground) blow up bridges etc. 120 classes using combinations of 3 classes with 1 primary, 2 secondaries (allowing you to have 460 different specs), you can't level up all the skills, which increases the amount of specs even further. Doesn't require botting/macroing thanks to this awesome invention of "Labor force".
