The english version of Priston Tale can be downloaded at eng.pristontale.com. There are already many versions of Priston Tale and servers are set up and already P2P in many asian countries such as thailand, korea, and I think China. Keep in mind that Priston Tale has been in the beta stage in the USA for about 2 years, and I've heard it was going commercialized, but any which way, they already announced free Priston Tale Gold until level 39 (that's still a lot of gameplay). 

Interface-The interface for Priston Tale I think is decent. They of course have visual display of your HP and mana. They have hotkeys assigned to check your character stats, inventory, and so forth. It is also real simple, click to move, hold your left mouse to keep moving, and left click on monster to attack, right click to use your assigned spell. The only things that really nagged me was that they only allowed 3 quick slots assigned to numbers 1,2,3, on your keyboard for use. Knight-Online I think offered 8 or 7, around there. Another thing about the interface that really nagged me was you cannot hotkey your skills, at least I haven't been able to during my gameplay, you had to open your skill window, and right click on the skill to assign it to your right mouse button. I give interface an 7/10, halfway decent, still needs some work.

Graphics-Now graphics in Priston Tale Gold are good for an anime-style looking MMORPG. The textures are detailed (unless you turn down your graphic settings for better performance), and there are barely any jaggies. Spell designs are decent, hacking and slashing does show some nice particle effects. Character creation needs to be more diverse, you can only select the 3 facial features of your character, nothing else really besides his/her class/tribe also. Character models are not really a biggie, they are decent in the game, a little diversity here and there. One thing that I did love was the login screen, the 3D background was simply beautiful. I give graphics 9/10, good, of course, but not perfect, lacking some diversity in character models.

Sound-The Sound in Priston Tale is good. I loved the background music, it really added the element of feel to the game. I turned it off mainly for performance issues, but the gameplay was simply not the same without the background music. Spell sounds are very diverse. Attacking sounds get repetitive after a while, but there are also a very diverse array of monster sounds. There are also good interface sounds that every RPG should have. I give sounds 9/10.
