You mean you don't use days and nights like in wm and slavemaker, just days? That seems too simply to me. After all, two shifts need more careful planning because of different customers tastes in different times.
And when girls are supposed to rest? Will it be player's duty to change schedule for each of them every several days?
Why do you need to tell a girl exactly what to do and when? I figure that we can introduce new system, a bit different:
Girl can do one 'large action'. That can be a fight in the arena, whoring, striptease, resting (like taking a day off, girl just lives a normal day every day, she rests, sleeps and so on, especially the once that are not slaves but simply working for you, I mean, you cannot expect them to do as you say day and night?)
Remember that this game works a bit different from SM and Otherworld. Girls have AP that they spend. Girls will spend AP during quests, during interactions, during preforming their jobs, I see no realistic way to put all of that in 'time of day' perspective, neither do I see a reason to. They do their main job when times suits them, but they do it all the same. One thing I am considering adding is 'Actions during the day screen'. Player could simply tell a girl to spend some time cleaning her room/building she is in for one AP per day, or to spend a number of AP recovering (taking extra good care of herself) each day and so on, you would have almost absolute control of what slaves do and eat and maybe even if they sleep at all but for free girls, this will be more limited.
I am not yet sure how to handle micro but it would be VERY easy to create a 'set to work and forget' system that takes care of a girl setting her to rest and heal when required and then back to the job.
If team believes it's important, especially since everyone is contributing to the game, a day\night switches can be coded in, that however would seriously mess with locations, quests, events and so on, cause every event would have to be coded in during evening, morning, night or daylight scenery and only available then. The way it is now, girl simply spends her AP as needed, if it's an evening scene, let it be during the evening, morning = morning. Easy to explain and not counter-intuitive. Also if girl works as a whore and event is during the evening for example, it would be easier to set a flag preventing her from working than having to specify time of a day for every single event in the game.
If we add a day/night shift system I think the shifts should be differentiated a lot more than they are in wm for example.
The day shift should have only a minimal amount of customers and should be more focussed on preparing for the night shift: cleaning the rooms, training and relaxing should be more efficient for example.
Logic tells me that girls that whored during the evening and night, sleep during the morning and take care of themselves during the day (Washing, making themselves pretty, chatting and so on). In my understanding the whole 'shift' approach that WM and SimBro 1x employ is not the best way to go and maybe even a bit stupid. In SimBro 1x it takes half of a freaking day (seemingly 12 hours) for a girl to take care of Hygiene or to rest and then you seem to control that but nothing else that she does... In WM you can have her do one thing per shift as well? So she does what? Cleans for 12 hours or whores for 12? Also if she doesn't whore (no costumers or refused), she recovers no fatigue for some reason... what does she do then?
I see no point in shifts, girls simply work the best that they can doing a job you tell them to do whenever time during the day requires them. For slaves you can use things like denying them rest and sleep during the day for extra AP but serious consequences as time passes (Heath, charisma, disposition effected and so on) but the 'flow of logic' is that every girls has a number of AP to spend working and doing events and rests + takes care of herself daily without you being any wiser.
Yeah, well, you might expect several customers in bar or maybe arena during the day, but brothel itself should be popular mostly at night.
Addressed that above, tell me what you think about my approach vs WM/SimBro 1x one. Other option is to use something similar to OW or SlaveMaker where there are more shifts and you have more control (Loads of actions) that can happen during those shifts but that would mess with locations and events as I said above.
All and all, I think one Large Action per day approach paired with a limited control to how she spends her AP has not been done before in any of SimBrothels and could be unique to this game if I am not overruled.
