One thing that I thought of before was how many US copies of consoles games that are actually sold in China. In the local games shops it's about 50/50 HK and US releases, to put it simple. There are also EU and JP versions but they are not too many, so perhaps 40% HK, 40% US, 10% EU and 10% JP or something.
We all also know that the console gaming in China is very very small, but the population is also very big. We also know that many buy or download pirated games, which takes away a part of what could have been sold games. And there's no official numbers to get, since it's all imports. So we have nothing really to go on at all.
But, just out of curiosity, how many US copies do you think are sold in China? Any guess is as good as the next, so don't be shy. :)
We could take take GTA 5 as an example, as it's a popular game here too. It sold 5.67(PS3) million in North America. How many of those do you think could have been sold in China?
My guess, based on nothing really, would be 50-100 000 copies, and thus about a total of 200 000 copies of all regions(HK, JP, US, EU) sold in mainland China.
