Didn't realize the ideas were actually holding you up. I have many! (I basically just lack the ability to animate them, more or less). Curious if you'd find any of them useful:
1. Title: Tiger Mom (like I mentioned earlier back in this thread)
2. Title: Kidnapped
Premise: Son is captured by 'random' milf for ransom. Mom must work together to find out who it is/where he is being held to rescue him. MC is the mom. Cops advise not to send money (kidnapper wants it sent via crypto). MC has 5-10 days to figure out who it is. During that time, kidnapper sends pictures and videos detailing what they will do/are doing to him in the meantime.
Gameplay: Movement around a small town and questing like seashell whispers/desperate days, puzzles, potential for fighting NPCs for information, or trading 'favors' for information or aid (maybe his friends or other teachers know something/are good at fighting).
Potential endings: Mother finds son (good ending), milf says time is up and steals son away to finally fully have her way with him (bad ending). Depending on how much work you want to do, there could be 2 or 3 different options for who kidnaps him (maybe a teacher, or the mom of a friend) that are either selected based on where kidnapping occurs in the beginning (user input) or all starts are the same and it's stochastically assigned at the beginning and the first clue or two you get gives you hints.
Alternative variant of this premise is that mother or sister is kidnapped and MC knows who did it, the question is how to find them. Same type of thing except more NTR heavy (though potentially avoidable depending on what you do in game).
3. Title: Family Business
Premise: Family runs a store. Opening is a mob-style shakedown. They trash the place, take most of what is worth value, and now you need to pay up every week or they do things to the family. (police are obviously useless when you reach out to them). Son MC makes most sense but potentially flipping between/having family members tag along (bro/sis/mom) could work too.
Gameplay: Movement around a city and questing like desperate days. Fighting enemies like in desperate days. Essentially try to find a way to earn/steal money and even form your own mob with friends (or convert members of the enemy mob) who eventually take the fight to them instead. Ending: Some sort of final boss battle and choosing among the harem of women you've accumulated (mom/sis, female friends, female mobsters, etc). If you lose the final boss battle or fail to make payments more than X number of times in a row, you get a bad ending where female family members are taken away.
