This is a good idea, there should be a built in peaceful or creative mode. Build a Wonder is a victory condition, in the game setup. Also, you can select Revealed Map and Explored Map. also in the game setup page. Also, in the game setup, if you click on the little checkdot that says Conquest, it will disable victory all together, so you can build endlessly.
As for the female citizens thing, two thoughts:
A: R28 removed female citizens, with randomized men or women models.
B: What makes men less sexualized than women? What about for most girls? They certainly think men are more... ahem... than women are.
