For example:Attack on titan steins gate VN and FMAB anime one piece manga
1)extreme foreshadowing but impossible to predict plotwists
2) Mysterious world which we know nothing about but slowly gets revealed to the protag along with the reader
3)dark grim environment although if it's absent it's still fine but I would love a darker tone
4) presence of a romance sub plot(to have some breaks in the dark story and giggle and kick my feet in the air)
VNs and LNs are welcome too…
