People will always find a way to get rid of our standards and put politics in our favorite things we love and have spent a lot of our money on them. (Too many reboots) The same thing can be said about video games. The other people will find a way to attack back.
Political ideology is about way of life. It's only natural for artists and writers to put their personal belief in their works.
George Orwell and Philip K. *** are 2 of my favorite writer and their works are full of politics. Disco Elysium is my favorite rpg of all time and the entire game is politics. It's the fact that the story includes author's worldview that makes it good.
A good story needs the creator to put their souls into it and souls undeniably means part of creator's life experience and world view. Aka: politics.
So I don't understand the criticism about politics in games. You can argue that the technical aspects of implementing those ideology isn't refined enough and it ended up becoming a bad game/story/world. But to say "games dev can't put politics in game!!!" To me it sounds like killing freedom of speech.
Goodbye Senran Kagura and Dead or Alive because the dev teams can't find a way to meet Sony's new standards. PlayStation is definitely not the same after they moved to California...
Did the dev actually said that? Because that sounds like excuses to me. There are tens and thousands of porn games on Steam, and Steam even has a much bigger userbase than Playstation.
If they really want to make sequels and Sony wouldn't publish, they can always publish on different platforms. There are absolutely no reason to publish on Playstation store only unless Sony paid mad money.
There are also a lot of ways to secure funding for a new game without Sony. Shenmue 3 was made using Kickstarter money. Wukong's game dev started as a 7 people company that took many years to secure the funding for a 140 people team too. Making a game that Sony doesn't like is very much doable. It's just hard, that's all.
To me it's just excuse or propaganda for not making a sequel due to censorship.
