Wonderking and Maplestory. Battle of the games.

Liked the game, though I'm not sure I would be able to sit through all that grinding nowadays. It also had severe problems with class balance.
IE: I had the "luck" of choosing the joker as my first class and at higher levels it took like 5 skills rotations to kill anything using decent gear. That plus honestly, the skills of that class were not very... efficient (that fucking scythe thing was a waste of a skill tree slot). The berserker on the other hand could bulldoze through everything and the skills were oh so much better.
