Thing is, this had to be weird.
I don't think a storyline like this would work as well if it wasn't.
Okay, Docs thinkyfacing me...
I'll clarify.
Imagine the MC being told by his dad that he has 23 sisters and he has to sleep with them in a game that takes itself super seriously. We'd have at least 5 or 6 updates while the MC has a crisis because incest bad and has to work things out with his female best friend who's always loved him but never told him and he's to dumb to notice.
Then they fuck because it's the only way to get early sex in super serious games because the main dish has to blue ball the players for at least a year.
Then we'll have 3 updates dedicated to each sister where they get to know each other in one, have little dates in two and then build up sexy times in the third.
Do this for all 23 sisters and you should have made a small fortune from the incest fans just in time to bleed dry the pregnancy fans when all the sister start sprogging.
All the while trying not to bore your player base because this is a super serious game remember, we'll have no whackyness going on in these parts.
Extra points if you work out which of the sisters is the fan fave and leave her for last, then run several updates where things keep going wrong and they can't get any alone time until you pull the trigger before the fans revolt.
Don't forget to add lots of drama because we're being super serious like ..... maybe a house fire, some shootings, a piano falling on someones head, you know, the every day stuff.
