Hollywood has a near infinite supply of original writers and source material to take from and adapt to film.

It could be argued that it’s less about creating content than transforming content (craft mastery and artistry is still required, but the concept is pretty different).

That’s also where I think Netflix isn’t that much in trouble based only on its business model.

But it doesn’t work with game creation. You can’t just transform source material (original or not), it needs completely different innovative elements.

To note, game franchises also exist, but while they are wildly profitable I’d see that as a well guarded niche.
