The September 16 global FAQ identifies a PC release and server locations in North America, South America, Europe and Japan. Turkish is absent from its language list. A translated community page should not be mistaken for confirmation of an in-game language.
Agree on the region before the character
For a group joining together, the useful question is not just which class everyone wants. Decide where you intend to play and which language you will use to coordinate. A shared region plan is more valuable than discovering after character creation that friends made different assumptions. Do not assume free transfers or cross-region group play without a specific announcement.
Check accessibility on its own terms
Our advice is to verify the controls and language you need before spending money. A PC release does not automatically settle every controller question, and a regional service video does not establish the features of the global build. Keep the official FAQ bookmarked; use it to separate confirmed support from features that players merely expect.
