Hack Clash of Kings
The buildings, nature scenario are similar to the style of European Middle Ages, and buildings are drawn in details in order to let players feel like battling in the ancient cold arms age.
Reputation grinds, ability pruning, stat 'squish', PVP overhaul, an emphasis on raiding, Garrisons' all highly controversial, additional content. This is really interesting, but also makes me feel not good when playing with my friends.
