I'm playing Goonzu Online now.
Only went to it after the game i used to play (wyvern) went down for maintenance, thats now going on for 3 weeks rather than the 3 days originall intended -.-
Goonzu has an excellent market system, ive never seen anything like it. Also, everything you find from monsters can, and will be used by people, who use the stuff to make armor, or medicines, etc.
Has an excellent tutorial too, im lvl 35 now after about 20 hours play or so now.
The game is at
http://global.goonzu.com/center/default.asp if anyone's interested. Do not download the lite version, it takes forever to autopatch -.-. Download the full version instead, along with the latest patch.
Oh, and name Kodos as the recommender if you do end up playing please
