quick question...

i have a quick question.

Is there only one large server (or world), or is it split up into seperate servers, and if it is, does it cost money to transfer from server to server?

there are different servers: america, korea, etc
it doesnt cost money to change but you can only change so many times (5?)

Korean, Japanese, American, Taiwan/Macau, European.

You have (5?) times to transfer servers. After that you are stuck in the last one you chose.

For European servers it's a bit different. Those servers are split into different languages, and I believe they contain English, French, German, Italian, Polish, Spanish, and some others.
