1.)Different apartments with their own events that make them more or less dangerous depending on the prices different landlords and rooms for sex, showering, and cooking. Showering would help mental health especially doing so just after work or something traumatic happening, and maybe an event where your bot asks to shower with you and thats how shower sex scenes start but just having her bathe you makes mental health go up a lot. It would be a good way to world build by showing other parts of the world your in and making having shit tons of money feel more like it changes your life.
2.)Have your bot make food for you if she has all the parts, some apartments will have windows in certian rooms allowing you bot to be more like a girlfriend or maid in apartments with less windows or more blinds.
3.)Having different and stable jobs depending on where you live like living in the "better part of town" gets you more money from different jobs, and the option to work one job full time so you can more reliably pay more expensive rent. Maybe have interactions where your bot warns you about your work and inturupts whatever you're doing waking you up or having a prompt show up while using the computer with options to ignore, go to work, and to stop notifying during cirtian activities, you can also tell her to not notify you tomorrow or something like that so if you want to sleep in she won't bother you
4.) having different stores to go to in "better parts of town" like they'll have food to cook with or clothing stores that are less sleezey, maybe a mall where so many interactions happen of all different calibers of money so it's impossible for the government to watch anything so they gave up a long time ago and people trade a bunch of illegal goods with a selection of shops where you can basically get anything in the game from the mall. It would be a good place to have a bunch of different interactions
5,)a shop where you can order bot parts to your house and they'll be there by the time you get back home, the shopkeeper offers to modify you bot to make her passibly human with a cost to modify parts to look human so she can walk around the apartment and maybe take her out in public to make your mental health better
6.)Being able to buy bigger and smaller boobs sizes would be the equivalent to colors and a module like hypercamo where you can have any bust size with more in depth breast physics the bigger you go
7.)Another modules like the first but it's for how chubby she is, like she'll get bigger softer thighs, stomach, breasts, arms, and face with chubby module s for arms legs and core. If she's big enough then she might jiggle while you have sex
8.)Air, water, and cum inflation where you can get a module where her stomach can fill with each thing, and they can have a bigger or smaller limit depending on the quality, the color being how big it is by default
9.)Then the normal sex without streaming increases mental health, im sure ur working on clothes and positions already, more medical options like to increase health directly, food options that you have to cook as mentioned in 4 and 5 but increase physical and mental health
I feel like 1-5 could help establish a huge class devide where the upperclass apartments make managing mental health and customizing your bot way easier but being impossiblely hard to get there, or for other kinds of world building. 6 and 7 help make your bot feel more like your own. 8 is just cuz I'm weird and 9 is the other stuff I saw and wanted and stuff that made a lot of sense to me
