I am playing wonderking atm, its lots more fun than maplestory. In maple all you do is grind for months, spamming 1/2 skills. I am only lv 35 (1-30 2day questing, 30-35 1hour farming a mission)atm and i have 4 attacking skills :P. I love the crafting system. There are dungeon missions, party quests, bosses/hero class mobs. What i like most about wonderking is the quests. Detailed discriptions, voice overs ect. Instead of grinding you can actually lvl by questing!!! There are alot more skills to choose from and more interesting builds to make instead of just pure str/luk/int like in maplestory.

p.s: even if wonderking is a copy of maplestory, i think its better than the original
