Personally, I have never played them before but there seems to be some Chinese VNs which is crazy popular for VN standard on Steam like Tricolour Lovestory, Gaokao love 100 days, or Our End of The World. The thing is they all have shit reviews on VNDB (below 6) so I'm not sure those games are worth playing at all.
What do you think makes these games so popular even though they are not exactly high quality work judging by VNDB standards?
