This is the best answer. Playing in established fictional worlds just means you’ll be paying the people who own them forever.

I’m experienced enough to know what I want. Give me tools that are good enough, like a more powerful Cities Skylines and I’ll just make my own.

That’s the dream. A combination of direct prompts, building tools and friendly suggestions from an AI to create something with just the right balance of sci-fi and fantasy to satisfy my tastes. Give me that I won’t give a flip about what a Disney or a Nintendo would have to offer.
