Ok in Ksro, you have a choice of making the ordinary chinese char like in Isro or european char. The Euro race has its own classes, skills, clothing, and etc. All chars whether euro or chinese co-exist on the same map.

A little of what of each has, just brief so you see difference between them.

Isro (International Silkroad Online, most play)
-Mastery Cap at 300
-Masteries such: (Fire,Light, Force, Ice, Bicheon, Heuskal, Pacheon)
-LvL Cap: 80
-All skills max at 69 (If I remember right)

Ksro (Korean Silkroad Online, who live in Korea play this)
-Has (Euro chars, map, clothing, skills etc)+Isro.
-LvL Cap: 90
-Chinese Char has Mastery Cap of 300
-Euro Char has mastery cap of 108
-Masteries or Classes of Euro Char: (Warrior, Rogue, Wizard, Warlock, Bard, Cleric)
-All skills max at lvl 60
Ksro has the all the map right now or whats released, but Isro doesn't have Europe map included yet. Heres some pics explaining the classes and weapons for each Euro class.
I have gathered all the info from suffering the net and looking at pics of Korean players etc. If I misspelled anything, sorry, I'm not the best speller. Also if you don't understand something, just ask I'll be glad to help. Hope that helps.
