Metin is infected by bots, however it seems the US version is more enjoyable.
Silkroad International is accessable unless you struggle waiting several hours in a "queue" line. If you ever make it in, you will soon realize that the needed SP (skillpoints for opening new attacks/buffs/w.e) that you gain from monsters arent enough to build a decent charakter.
Silkroad International is infected by gold and playerbots, there are no handplayers or at least much handplayers left there.
Silkroad International is a moneyCow for Joymax (Owner of Silkroad) and whatever you do or want to do, you have to spend money .. lots of money .. even a VIP access called premium is money.
If you got enough money to spend, you might have some fun in this version of Silkroad.
Silkroad:
+Fun to play
+3 Jobs to choose (Merchant/Trader, Hunter which protects the Trader, Thief > imo the funniest job out of these three)
+Nice graphics
+PvP system aint bad at all (as long as you really do 1 vs 1)
-Needed SP is hard to get by yourself
-Needed EXP after a certain lvl is really crazy (you kill 3-5 mobs for 0.01% exp. p.)
-No need to go for UniqueMonsters or PvP before reaching higher lvls, you will just get ripped and be frustrated
-You will lack on gold since items are expensive (if you start from 0)
-Silkroad International is meant to get played by different players from diff. countries, however you will encounter lots of racism (especially against turks, if you are a turk bad luck then .. dont take it personal ^^)
In the end i WOULDNT recommend Silkroad International, unless the CEO's change their game policy.
If you really insist playing this game, go for a foreign Silkroad (same game in diff. language i.E.: russianSRO, chinSRO, koreanSro, and so on, ..) which let you login at least without waiting hours..
