I have a few ideas. Management games in the style of brothel games and dating sims. Expect stats stats and more stats.
Concept one:
Inspired by soo cubus, a game where you are a girl just trying to pay the rent. Be the prostitute, raise stats and make money. Pseudo random events.
Concept two:
Criminal stimulator. You are a down on your luck loser. Your last regale is to use crime to get sex, drugs, money, or D. All of the above.
