typical korean mmo, sexy graphics especially in trailers, ingame the characters look ok. lots of character optimisations, but the gameplay is just a boring repetitive grind fest. usually nearly no quests and no real story just slaying hordes of mobs with near to no KI. plus an item shop for buying things for reallife money.
some people like it, but i prefer mmos that don't put all money in eye candy and add story and good gameplay as well.
I'm glad you've played it and can authoritatively say it has shallow gameplay.
Can you do Diablo III next? I'd love that.
PS: I could swear I've seen this game/trailer before.
