A question for the players, do you prefer:
- a game where MC impregnate female characters;
- a game where MC's wife or GF risks ti be impregnated by others.
Of those two options? Definitely the first one. Netorare and cuckoldry are big turn-offs for me.
I really prefer games with female MCs though. There's just something unique about seeing a strong lady adventurer stride out, full of confidence, into a dangerous world thinking she can conquer it... only for her to bite off a little more than she can chew and/or submit to temptation. In Night of Revenge, for example, Aradia is a kick-ass witch and she's convinced she can handle anything the world throws at her. But she's also naive, and there are plenty of scenes where one misstep leads to her downfall.
Impregnation adds an extra layer of spiciness to that scenario. I've created plenty of female characters in Skyrim who can slay dragons with the best of them, but somehow wind up getting kidnapped by creepy cave-elves and forced to breed with insect monsters. Somewhere, Todd Howard is shaking his head in bitter disappointment.
