Being 'American' or not has nothing to do with ggFTW forum. Yes, technically, we are an English-speaking community but we don't limit our services to English-translated MMO only. (See SDGO section for example)
Riolu is correct to say that it would only make things more complicated if we separate the sections by publishing companies. There are at least 5 companies that publish Grand Chase (South Korea, North America, SEA, Brazil, and Thailand) We'd end up with at least 5 different sections just for Grand Chase. It'd be more of a hassle than anything.
