Serious question: If you take away all player agency, rpg mechanics etc, and basically make this a kinetic novel (what the game currently is), and I agree, this is probably the only way this game will have at east some very minor progress, what is left then?
If you take all that away and make this a pretty standard slutification novel with a small spy mission thrown in now and then, is this something you all are interested in? I'm not trying to senselessly trash the game, but I'm seriously wondering. Sure, the writing is definitely above average (outside the sexy parts, I don't think this "game" is particularly sexy), but other than that, I really don't see the appeal of whatever is left of the initial premise.
I don't think anyone really wishes to take out certain mechanics from the game. But those mechanics should do something and adding more (by reintroducing life path) and not using them can be viewed as a waste of time, in a game where the story progresses at slower pace. In my opinion you could achieve a far better game if you use what you already have and create some narrative branches based on that. For example:
You can start with two main ways of playing the agent. The perfect agent path - an agent that is very good at being a spy and knows how to use every tools that she has, from physical spy tools to sex appeal, in order to get the mission done, while avoiding sex as much as possible. The novice agent - an agent that is not too good in the field, she has to compensate by extracting as much information as possible after sex.
The first scene with Conner could look a lot different. The CIA is not stupid, it knows that they need to infiltrate someone in the club and the best way of achieving this is by creating demand. They somehow made a current bottle girl leave the club. Now Conner needs to find someone to replace her, which means that he doesn't hold all the power during the casting scene. Let the agent choose how she wants to move forward. Will she refuse Conner completely? will she play hard to get and attempt to befriend Conner (the boss) by offering a BJ and letting him want more? Or maybe she will let Conner fuck her, because she is afraid that there is no other option. Out of this 3 option, the agent that went on path B could end up keeping her job as a bargirl just because Conner wants her all for himself. Making her a bargirl would mean that he looses her.
Split the birlgirls in two groups: some girls that enjoy their lifestyle and the fact that it is easy for them to make money and other that don't, but know how to handle the clients in some other ways. They can look only for generous customers and lie that they want to marry them, or just seduce them just by dancing, or doing softcore stuff. If you are a really good friend with some girl, you can turn her into an asset. If you are not, maybe she will try to compromise you and you need to take care of her, sabotage her job. If you proved that you are a good agent, the CIA could offer you a certain budget. You can use those money to pretend that you went out to an outcall: CIA could fake call Miss forgot her name and ask for you. You leave the club for an hour and later return with the money. Is this good fap material, no. But at least you'll have a choice. That combined with the fact that a birgirl will have an easier job to get information about the Develfish vs one that sticks to the bottle girl position and has to do more spy missions in order to get the same information. Each spy mission should also be harder and harder. One mistake and the Thai Organize Crime will catch you and the story will end.
So I don't know, I think you can create a story without knowing if your first part time job from high school was in a restaurant or in pizza hut.
