I like it when a protagonist is
flawed. That isn't in the first place about ethics, but I don't like a completely pure good protagonist, and I don't like a dark and edgy one who has massacring kittens and puppies as their main goal in life either. What's more important to me is that their ethics are grounded and fitting, and I can, like, put up with a lot of stuff I don't personally agree with because I don't self insert. There was an abandoned VN about a king with a lot of implied incest, and he treated his lower servants with a level of fitting contempt for a royal or noble ruler in that kind of society. Another VN had an office guy who had sexist opinions about women driving. That stuff felt real enough. I don't like grimdark protagonists either because those are very often overpowered dark Gary Stus.
Those protagonists are usually male, the dark Mary Sues of grimdark games are often demonic antagonists called Lilith or Jezebel.
Likability is a real thing, tho. It's one thing if the protagonist is a literal pirate who does actually
do piracy and murders crews and loots the cargo. Or like a slaver or slave trader or slave owner who treats his slaves cruelly, despite being a former slave.
Yes, that's something that happened, people. A lot. But randomly murdering without any available or implied reason overplays likability.
Unless they're ugly bastards, I'm talking about the victims. The 2 examples I just gave are honestly prolly too much for many people tho. It's like a
very subjective standard indeed, but I think it's a better guide for how good or evil a protagonist can be than a literal ethical standard.
A thing that looks like it conflicts with what I just wrote is that I don't really like exaggerated negativity. But I've realised that's often negativity that's way beyond anything that's justified by the setting. On the other hand I'm more lenient to "too evil" protagonists if the game feels like a satyre.
The netori versus netorare angle was a bit of a twist. I honestly dislike both, though I may put up with netori if the protagonist is a enough of a "good guy",
this is a very low bar in this genre, and the "cuck" is way worse than just a jerk or a neglecting partner. I generally don't like cheating much, and that includes emotional cheating where an MC tells half a dozen women "I love you" a dozen times when that obviously implies romantic love and commitment. Ironically, I can like some betrayal arcs where the element of emotional cheating is ambiguous, or where the wannabe partner is too entitled.

And tragedy is fine.
In short, flawed, grounded (consistent), likable. Not too negative. No like cheat cheat and emotional cheat.
Good point, but I think in most of those cases the father or step whatever is an ugly bastard? If not, add it to the list!
There's a
dedicated trope for that, if a dad is alive in a game with a male MC he's often a sociopath (may run in the family!), especially in incest or harem games.
Once in a Lifetime is an exceptional one where the dad is a jerk from the start,
literally Satan, possibly cucked by the MC, and killed by the MC in the end. No Fräud jokes!
Starting to feel this weird trend that seems to be emerging in this thread!
I'm glad everyone is against this thing that keeps being brought up though. Keep being honorable and good!
For their defence, there are games that are literally like that. Often dark and edgy netori. There's also a way overrated one with a bullshit dilemma where the protagonist is forced to choice between raping a young woman close to him personally or let her get gangraped by monsters.
I can even burden you with a game where a female protagonist uses hypnosis to get her lesbian harem, and another one where a female protagonist manipulates and abuses her slaves to train them for her lesbian harem.
