i can only give this game 1 star rating review to all download app store, this is not for free to play players game but still you can play this game and i don't recommend that you spend money on this game for free to play players, monster card drop rate is very low or zero, refining equipment even from 1~4 have a very high chance to fail, too many dead servers but its a good thing because you don't have to compete with other just to gather materials, life skill consumes too much time and too much effort to do specially fishing
