OMGosh! Thank you for posting this.
Wonderking was absolutely a great game to play. Way better than Maplestory and any side scrolling MMORPG.
Crafting - Wins me hand down. There were so many things to craft and you can level up your occupation and craft even better things. At first, it may seem impossible to reach but once you have your guild donating their mats to you or newbies selling it you. Everything is so easy!
Guild - Guild was lovely as it was for me. Guilds back then were actually people who cared for their members. Giving handouts or passing down their equipment. Helping out on bosses and etc! As for me, I was their crafter. Everything that needed to be crafted were passed to me as my crafting was maxed. There were a time limit of a month for non-active members to be kicked out. Guild was awesome.
Class Jobs - One word. AMAZING. There were four basic classes and each has their own pro's and cons. + When they equipped their class armours and upgrade to a higher class. I've never seen a toon of Side-scrolling looked so amazing.
Skills - Better than Maplestory. Short cooldowns and combo =) You could skill chain a mob.
Other part of the game - There was auction house, hunting was relatively good. Boss were given a special room so people wont have to fight for the boss. Equipment drop rate was good too.
To sum it up, I loved this game and when I found out from your post there was WonderKing 2, I cant help but register to Onrpg to tell you the things has to offer! Hope Wonderking 2 will be better!
