She is really strong in her own ways (at-least not so much from a physicality POV), but then again people can be strong in so many different ways. And Zahra's supporting/constructive nature is just one of her many strengths.
Yes indeed. Being really feminine does not mean weak willed. Although a feminine woman may not easily resort to physical violence herself, she may well manipulate others to get what she wants.
Which complements a guy like Zaton very well. Zaton is definitely not just dumb muscle, but I do think he is not the most politically apt person either and that's why he needs Zahra.
I think there are already plenty of games out there with weak (willed and physicality) main characters..basically every game with a school setting. It is nice to have a main character who has more than just a magic penis/power/potion, but who can actually kick some ass and isn't afraid to use physical force and intimidation to get what he wants. This is one of the things that sets Desert Stalker apart from the rest and it makes much more sense in a post apocalyptic setting than playing as a weakling. Btw, the game does give you several options throughout to take a back seat if you so choose. I avoid them because they are unappealing to me, but they are there.
You can be simp to the queen, you can step back while Zahra assumes a more dominant front in several scenes. In bedroom activities, there isn't any full dominatrix content, but Shani shows off some early tendencies and the dev is apparently teasing future dom/sub content with that collar business. None of that is to my liking, but for people on the opposite end of the spectrum, it is available.
I fully agree with you that it is nice to have a confident, capable and sometimes ruthless MC for once instead of all the highschool sissy bois.
However, within certain contexts, I do think it's interesting to have the MC take a bit less domineering role in the bedroom. With Zahra, he has nothing left to prove. With the Queen, well, she is factually more powerful, so...
Not sure what you mean with the collar thing. If you are talking about Ain, I also don't that, and I think Zaton also dislikes it.
