In many ways, Tera is a whole lot like other massively multiplayer role-playing games. You team up with other players, fight monsters, level up, earn new gear, and so on. It is, in fact, a very traditional online fantasy adventure in most respects but one: its action. And that action is so smooth, so immediate, and so enjoyable that it's likely to keep you invested in Tera, even as you skip from one quest to the next, ferrying messages between characters standing 20 feet from each other. Generic questing aside, Tera is a well-executed game: it's easy on the eyes, smooth under the fingers, and remarkably stable.
