You see, most MMO games use a paid system where there is no other way to get premium content than to pay for it. This game offers contracts, or rather, challenges in-game, and some challenges pay the premium currency. That's what I call a good move, because for people like me who try to spend the least money on MMO or MMORPG as possible, it's a notable pro for reviewing. A good game, good weapon system and skill system.
