I have started playing Crusader Kings II. The game is set around the 8th century through to 1453. The idea is to manage your dynasty through the timeframe. It's sandbox though. Tall, wide, peaceful aggressive etc. It's a grand strategy game where you can go forth and crusade against the heathens (whoever they are) but there's a lot of RPG elements as well. The inheritence laws favor men, and female and gay rulers have penalties on opinions with vassals and rulers. Succession laws vary by culture but generally it's male preference or male only. Islamic rulers can have 4 wives, Vikings can enslave consorts and have children with them. A male ruler can take multiple lovers and have children with them. A female can also do the his but she is limited in the amount of kids she can have. If your dynasty gets decimated a male seducer can have 10 or more kids and ship them off to marry Duchesses which their kids will inherit. Women can marry matrilineal but you're generally marrying down or you have to invite males to your court to marry. But looking at the time frame things were rough back then for women. However. 1. You can switch the laws off before ganestart. 2. You can play as is but pick the right culture or religion to have female rulers. 3. You can focus being tolerant and change your succession laws where women inherit on equal terms (1981 IRL). This will take a while though. 4. You can become a heretic. For example you can be a Cathar and have female rulers, bishops etc. The most common way to have a female rulers is to have no eligible makes in realms that allow female rulers or an elective monarchy where you tend to pick the best ruler based on meritocracy and convincing the other nobles to go along with it. You can also go on crusade and pick a member of your dynasty to get the realm assuming you win it. I had a Crusader Queen with the right traits and decent combat skills. She was my Joan of Arc of Jerusalem. She could duel the men and due to her crusader Queen traits and slaughter the infidel trait she spent most of her reign fighting off jyhads and holy warring the Muslims. So wrapping it up you can play ahistorical and a lesbian Basque or Cathar Queen can totally smack the men around and reign in her own right along with her daughter's. A Cathar ruler could holy war her way through Europe. A Basque Catholic one could fight in crusades et. You can also smash the patriarchy by destroying the church and shattering the popes moral authority. This will make Europe a free for all heretics, holy wars, anti popes or even turning the Catholic Church into heretics if you have the Byzantines come out on top. So sexist, sandbox or something else?
