this game is very famous in several countries and continents and even asia. Surely not everyone knows English, so developers add several languages to this game. But unfortunately the language in this game is still lacking, because many of the majority countries use their own languages more. Therefore I give recommendations for several languages that might be suitable to be added to this game.
-Chinese(中文)
-Japan(日本)
-Hindia(भारत)
-Indonesian(Bahasa Indonesia)
Just this my recommendation to added more asian language.
