As a game designer the answer is very obvious: That's hard work!

As a heavy LLM user there is another obvious answer: The LLM is very good at copying.

I suppose those are two sides of the same coin. All the hard decisions and all the creativity is already done.

Those aren't the only options though. I've long told people that want to get into game dev that the best thing to do is mod their favorite games. I'm hopeful that the technical ease to do that now leads to a lot of human creativity being expressed.
