http://pwi.perfectworld.com/ is the website for the game.
You register and you download... its like 1GB download size...
It's a game where you can have lots of fun even though after some levels it's kinda hard to level up... You have alot of classes you can pick of... Warrior/ Werebeast / Assassin / Mage / Cleric / Physic ( dunno how to spell )
I played it till like lvl 60+ ...
Got kinda bored of it but if you are bored of IMVU all the time, i suggest u to try it out and play it !
