I see that the main theme of the game is revolving around the fact that the MC is the last reproductive male in a world of women. I would add a bit of topicality and suggest such an idea. The game would be called "Planet of V."
The protagonist, an astronaut who is separated from the flotilla and drifting in outer space, spots a blue planet suitable for life, where he could replenish supplies and make repairs, but his passage through the atmosphere is not without consequences - his ship suffers more damage than he would expect, he makes an emergency landing and loses consciousness.
When he wakes up, he notices that he is surrounded by a crowd of dirty and untidy women, all of whom are overweight and physically ugly, in this scene you can spot the statue of liberty in the background. The women are discussing the "unusual" appearance of the woman(MC) they found near the smoking iron structure, they are convinced that such a strange and attractive girl will allow them to rise in the eyes of their queen, the goddess of beauty.
The hero is taken to a palace built of sticks and dung, where he is granted an audience with the local deity - the ruler of all the women of the land, the goddess of beauty the queen - a typical body-positive, oily-haired fat woman, riding a cart from Wallmart. At first she admires this new girl's looks, until the local witch - a wrinkled, one-eyed old woman - enters, who takes one look at the MC and yells "Man!!!" Admiration in the fat women's eyes is replaced by disgust and anger at the man responsible for their unenviable plight. The MC is forced to flee, luckily he runs faster than the cart from the Wallmart, so he escapes, but he still has to get out of this city of women. Luckily he comes across a strange figure on his way whose every movement is full of grace, wrapped entirely in a veil - one of the outcast - an ugly maidens whose sole purpose is to serve the exalted queens, cleaning, cooking and laundering. Taking pity on the MC, she helps him escape and takes him to their hideout. There he meets these members of the outcast. At first they are ashamed of their ugly appearance and behave secretly and insecurely, but he manages to persuade one of them, the one who saved him, to show her face. The MC faces a graceful and beautiful young girl who could have been a top model, she weeps with shame because she has no idea how beautiful she is, because all her life they have been called ugly. The MC soothes her as best he can.
Anyway, after getting acquainted with all the local outcasts, all of whom are top models, the MC is taken to a laboratory where a single scientist is cloning biological material to reproduce life, but this material is defective and only women are born from it. The MC has a choice to leave everything as it is or replace it with his own, which can also give birth to boys. He will also have to destroy the tyranny of body positivity and return hot beauties to the Olympus of fame.
