If you only play one free 2D-based side-scrolling MMORPG Korean made game this year, make it Maple Story.
The graphics are cute anime characters, complete with cute anime enemies, together with cute anime backgrounds.
The music and sound is fine, but repetitive, and you probably turn it after a while. By far, nothing thought-provoking, but suits the game.
And finally, the gameplay; can you say, “extremely monotonous”? Well if you can, then you got the just of this game.
PS: Believe it or not, there actually more than one 2D-based side-scrolling MMORPG on the market.
