1. Introduction Sango Heroes 7 is a turn-based tactical role-playing game (RPG) based on the Chinese historical novel Romance of the Three Kingdoms (Tam Quốc Diễn Nghĩa). While the game was officially released in Chinese and Japanese markets, it never received an official Vietnamese release. Nevertheless, a significant Vietnamese fan community has embraced the game through “Viet Hoa” – a grassroots process of translating and modifying the game interface, dialogue, and mechanics into Vietnamese.
