Brenda will get what the (3 days old) Patreon post announcing it says she'll get.
So what you write here is player created expectations / not going to happen.
So she will, as announced, get content anno 2023 that is unique to her, instead of a copy of some other girl's old content. She'll be a lot happier for it.
And it is a good thing girls do not all do the same, because it'll kill the game (same for all takes years)
She will be completed once the announced content is done, which is by the next release, version 4.0.
As I said in my edit, I'm not calling for the creator to do anything he doesn't want to do.
However, the things in my list are what the other girls get, and Brenda should get as well.
You can say a girl is "completed" because she's not going to be worked on any more, but until those boxes are checked, there's room for growth.
As to your objections: the options each girl has aren't just a copy of each other girl's other options. Take playing in the pool, it's different for each girl, but that's the joy of the game. The little differences create variety which is what makes the game good.
I know you can sit with Brenda on the lounger, but she could be like Desire and have the lounger option as well as being able to play in the pool.
While I don't want "all girls doing the same," because I value the little differences in each scene. However, if every girl had a copy of the topless yoga poses to give them a yoga option, I have no idea how this would kill the game. Though perhaps I misinterpret your meaning here. Can you give an example?
I can see how filling in all of the blanks could take years, but the creator expects the game to take a long time to finish, and I don't mind waiting. If Brenda is "done for now" and might see more in future, that's all I want.
Anyhow, I hope I have courteously clarified my thoughts here. Know that I don't expect to influence the game, I just want to advance the discussion among the players.
Thank you for reading.
