Anna could become dominant. For example, first MC would offer her this game, where she is dominant. Then, with each new game like this, she would become more confident and she would like it more. In addition, she could remember the past and this could be additionally partially like revenge. In parallel with this, it is possible with the help of a psychologist. All together, this could make her dominant and bossy over MC and others.
I would like to see Anna as dominant and bossy.
I would also like to see more scenes with dominant Rebekkah and Shanaya.
(On the FemMC route): FemMC can be dominant and bossy.( for example: she could dominate over Rey,...)
The advantage of keeping an eventual dominant role for Anna contained withing roleplay sessions is that it doesn't require to branch the game. If Anna were to develop a more permanently dominant personality, the game would have to account for that in terms of events that would no longer make sense to trigger, variations of events and new events with her. As I understand it, that can quickly spiral out of control once you start to consider other NPCs having evolving personalities as well. It's one thing to make certain events trigger once relationship (or other stats) passes a certain threshold, but to completely change an NPCs personality would require a lot of extra work.
Having said that, I think a lot can be done with triggered or random events that let you explore each NPC in a more complex and 3D way, without changing their fundamental traits and routine. This imho, ofc.
I'd also like to see more dominance in NPCs *as flavour*. That is, not a submissive player route, which would probably require writing a parallel game, but more events that can spawn or scenes that you can ask of your household. I'd love to see more games pick up the Dijkstra and Philippa theme from The Wicher (TV show). A powerful lord that secretly submits to a dominatrix is appealing
I see that theme apply to this game like a glove, especially once MC feminization content gets added. While you're still the master of the house, because that's the main theme of the game and difficult to get around, you could pursue your kinky side in a variety of ways, including submission to (one or more of) your slaves. I see this happen in a "light" and reversible way, only insofar as the MC wants to.
Other games where I see this being attempted (with a change in events without changing game mechanics) are, for example,
Wife Trainer Files (where multiple of your trainees can become dominant and at least one can dominate you, while you keep on training wives) or
Whoremaker (where you can become submissive to one of your whores, while still running the brothel). Even the infamous NTR that bothers so many, so much, could be explored here in the same spirit, probably netorase rather than netorare, with you allowing/encouraging your slaves to call on others for sex, to tease you. Everything optional ofc, where it comes to debauchery, the sky is the limit
