i looooveeee incest routes!! especially if the relationship is treated as kind of toxic/codependent, i adore to read about taboos (plus i dont really see myself as the MC so its more about shipping to me) ((and i obviously dont condone incest irl))
imo three or four, i feel like in games with lots of LIs the creators' biases always show and while some routes are amazing others are...just...there.......(also as a completionist i tend to get overwhelmed ww)
i only like younger LIs if they are at least 18, but i dont really care if they are younger than that when the MC is around the same age as well. I dont have a problem with others liking lolisho, but that does personally make me uncomfortable TT
Hakuoki and thats because i actually started playing it on my 3ds some years ago and never finished it and now i would have to replay everything bc i dont remeber a single tjing...
To me the MC is super important!! I don't really project myself onto the protag therefore to me she is just as important as the other characters and I need her to be interesting for me to get more immersed in the story (´͈ ᵕ `͈ )
