I have a friend in HK who I met up with (pictures of him may or may not arrive) earlier today...
And it seems he's in the process of making a VN somewhat based on Hetalia. Unfortunately, I don't have any CGs on hand right at the moment, but his art (he's doing all the CGs) is holy shit it got so much better than the last time I saw it, it is unreal xD
The system appears to be nearly done, it seems that the major work is on the script and CGs, as I managed to get a glimpse of the thing in action. It's not bad! I expected it to be in Chinese, but it is in kinda borked English xD
