Square Enix's 1st MMORPG created a while back that use to be pay to play, but now free to play; FEZ is one of those MMOs that aren't realized for their graphics but are realized for their gameplay. It's a War-type territory conquering game where you capture another faction's land. The more land you get, stronger you become, the better weapons you access, and more bragging rights you have (personally.)
There's 5 factions so there's constant wars constantly going on. There's 3 classes: Warrior, Scout, and Mage. You can summon advanced classes to help you out in the battlefield like knights, giants, or wraiths; and each with different weapons and skills. Later on scouts will have guns and whatnot, the game is overall fun, I enjoy it.
The vid above gives great information on it. If you play it, I'm in the faction, Hordaine IGN: Yuen. I give it a 4.5/5
