Alright here is my opinion of this game, and my comparison to WOW.
The game is alright. It is fun enough, as long as you don't mind grinding. There are quests, although they just require you to kill mobs and collect their claws, skin, teeth, etc...
Pros : Fun classes, Nice diverse races, easily picked up, nice environments, overall enjoyable and simple.
Cons : The translations are horrible, beyond horrible. And they have voice acting that has Engrish. The game tries to look and work like WOW, and fails for the most part on the things that actually count. The actual skill set up is really not that great. And the movement controls are mediocre at best.
Now, the comparison.
Ok, what they did was try to copy major components of WOW, and integrate them into their game. They did achieve a level of success that makes the game feel slightly familiar with the games controls having played WOW before. What they didn't do was make the game play as smoothly as wow. It has a certain jerky, broken up feel that is very common in asian-style MMO games. I wish I had a better way to describe it, but I don't. As far as looking like WOW, well, it doesn't. I'm sorry if you thought it was a WOW clone, but it is simply not. The game looks all its own as far as style. It has a look more akin to Perfect World than WOW people. They made the screen shots and some of the spells shown look very, very similar to WOW but overall the game doesn't look at all like wow, and in my opinion quite a bit worse. The classes are also very close to those in WOW, as well as the skill trees (which don't function very well to be totally honest).
So if you're looking for a game that plays and looks like WOW, this isn't it. Just play WOW people. There isn't a game out there that can be put into comparison and come out looking good anymore. And don't get me wrong, there are MMO's out that are good, but they just aren't anything like WOW. Example: City of Heroes, It does well and has a large player base, but it is nothing like WOW, it simply is a different type of game, and you can't compare the two.
For a free MMO this is a good choice. One of my favorite to date thus far. on a 1-10, I give it a 7. The reason it isn't higher is the horrible translations and the voice acting that needed to be left out.
For free, and a Gig of space, its worth a few hours of your time. I know i'll be spending a few more hours in the game.
And Rice Eater, I saw you in the start zone. My name is Krissy, and i'm a Human Archer. I saw your name and laughed. That could be considered slightly offensive to some in that game I would say. There were a lot of non-english speaking players on while we were.
