It's like WoW, but instead of fighting countless of AI mobs, players fight other players in epic battles over the control of castles and forts. "Allies. Enemies. Empires. Betrayal. Risk. Conquest." Crowfall is a medieval fantasy PvP-focused MMO. But there are many other things to do than PvP: complex crafting, exploration, hunting and gathering, hauling (caravans), city building, politics, quests from the gods... Beta has just begun and it's free to anyone who wants to give it a try.

Here's a video showing the game : https://www.youtube.com/watch?v=Dk9C1yDfF0U
