Perfect World is almost perfect.
The graphics of PW almost reach that of WoW, almost. The sound is also good. The gameplay is pretty much like WoW's, click on the monster to see its level and attribute and attack when you want to by clicking again. There are also many skills in PW, so the fighting isn't always double click and wait.
Unlike most MMO's PW leveling is fast and does not take forever like Maple Story or Silk Road. Although walking around is slow and boring, when you have a thing to fly on its fun to move from place to place, at least for a while.
The boss battles are hard and the crafting is slow to level but besides that its pretty much perfect.
Overall, a almost perfect game which is called Perfect World, and also is not being played by half the population of Korea.
