Tera online sucks. I bought the game, tried the beta and returned it. Today is the release date in the united states for it. So the price is going to go down a lot soon.
But either way, if you wanna sucky camera view, sucky movement control, have to aim spells and arrows with your mouse (which also moves your character at the same time), then this game is for you.
It is not the classic WASD format because you cannot turn properly with the keys. Its all about the mouse / PC controller.
