It's got a few bugs, but the combat system is the most advanced I've ever seen with a great use of blocking techniques, bows, guns, and shields, all on foot or on horseback. You can wage war, manage kingdoms, offer peace tributes, hire nobles for your lands, and slay all who stand in your way. It isn't free, from a legal standpoint, but if you want to download it for free the virus-free link is , get utorrent to download the torrent from
Have fun!

Edit: and with mods which are due to be released soon, you can manage your kingdom in greater aspects such as sending armies to attack places without being there yourself (this one is just a possibility) and setting taxes and organizing your armies better, choosing who goes into battle and what they do, that sort of stuff.
