Well if you are a Pangya player my first suggestion would be to try out SG's other games (since you can just use your existing account)
Which are grand chase and trickster.
I'm a long time trickster player and would definitely say that's worth a look.
However if you are looking for something that is more graphically similar to pangya I'd suggest trying a 3d mmo.
In which case you could check out gpotato
games (flyff, iris, aika etc)
And perfect world
games (perfect world, forsaken world, ether saga etc)
