why? We no play KO Taiwan and download game client, Why is that, too?
A Taiwan based company is launching open beta for KO Taiwan within the next two weeks. Because of that (I'm just assuming here) they could have decided to block players from China on KOW, due to licensing issues. If they have the license for serving Taiwan + China, then they can demand mgame to block Chinese players from accessing this server.
Of course this is just an assumption, someone from NTT should answer this.
