I've seen in Chinese communities like Minimetro in Baidu Tieba that most Chinese players want Guangzhou to be added to the game.
Guangzhou, a major Chinese harbour city on the south coastline of China, ranked 37th in GFCI, has just celebated its 20th anniversary of its metro. Guangzhou, like Montreal, has a landscape featuring rivers cutting land into many parts and forming isles, making the city a recommendable map for the game. Since the opening of the first segment, with the blooming economy and the boost of 2010 Asian Games, the metro network has developed into a large network of 8 lines, 1 APM, and an intercity metro. These lines sum up to 186 in number of stations, 306.8 km in length, and has a 7.36 million daily ridership and an annual 2.568 billion ridership. Now, there are 215.37 km of lines under construction, meaning that Guangzhou metro will develop into a much larger system in the coming years.
So much for the introduction. Chinese players hope Guangzhou to be added to the game!
