The game has around 3,000 pages of dialog! It is about as much work as translating all seven Harry Potter books. One person translated about 1-2% of the game into Chinese (about 50 pages worth) which took them several months.

If you want to try translating the game yourself, it is open-source! Most of the text is in places like this "AbraDialog" class. Good luck!!
