Wildstar is a New MMO made by the guys at Carbine Studios.
Carbine studios is a New company filled with tons of MMO Vets who made tons of mmos like World of Warcraft, Ultima Online, etc.
It is trying to combine old school mmo ideas with brand new gameplay designs. No World of warcraft esque fighting, it mainly is using AOE/Telegraph combat.
The Game Is filled with tons of content apparently, you can take on a combat role and beat the crap out of stuff on the battlefield, you can be a explorer and explore new lands, you can be a scientist and research animals and stuff, or you can be a settler and build upgrades and new buildings on towns in the game. These are not the main classes.
They also promise Massive amounts of Endgame content for Solo players, PVP Battlefields that players can build themselfs, and Raids that use common sense rather than a Dance dance revolution copy paste that most MMO's have.
