The tactical MMORPG Wakfu is set to release February 29th, 2012. I'm pretty interested in this release because it has a tactics RPG combat system as well as open PvP and a player government system. Essentially a sandbox game, players can destroy or repair the ecosystem through the addition or removal of plants and animals. Players can also run for Governor, who is responsible for law and politics between the 4 nations. For the more daring, you can become a guard or a soldier which has bonus damage against outlaw players or in territory fights. The game is F2P with a $6 subscription fee to access premium content. Additionally, there is a cosmetic cash shop, which in my opinion, should not exist because of the subscription fee. Wakfu is currently in open beta, though they are not saying if the US version will be wiped.
