and what's this DDO 9D
can somebody explain me all the above please?
thank you!!

i like to know too

I don't know the exp for Thai 9D(check those Thai D9 threads and those sticky), but the Vietnam 9D closed long time ago.

DDO(Dream Dragon Online) is the chinese version of orginal 9D with a twist like a normal chinese MMO (mounts, soul pets, etc.). There are videos that shows you some of the game play, so you can see what the graphics are like, it's abit different than the original. DDO just finished their 1st round of CBT, so waiting for the 2nd round of CBT, don't know when that will be as they haven't post a date yet.
