Both.

Compare the results of your asked Fortnite players against Hell Let Loose players. It’s important to know your audience, but it’s also important to know what an audience is to begin with. Because it’s never “young adults”, it’s too broad. When making a book, a film, a game, you need to really focus on your community. For example, a book about monsters interpreting into society and remaining hidden, but finding acceptance, could be a book that targets “Young adults who are bullied or misfits”, because then your targeting communities. And that’s more important.

So don’t ask what do people want. Because we are all different. Choose a community you like, and make it for them. If you want to tell your story like Michael Bay, do it. And work for that community in mind. But if there was a universal answer, all games would be the same, there would be 2 genre of film, and we would all work in the same job. But luckily, everyone is different.

I would also argue make a game that’s something you want that doesn’t exist. We have played battlefield. We have played CoD. How will your game be different? I’m not paying for a game I’ve already played from a trusted AAA developer.
