There's enough story if they mainly focused on the Zero Dawn time period.The games have enough story to support the gameplay and art direction.
They don't have anywhere near enough story to support movies or books. What memorable characters? What deep interaction?
I guess if they just want to make a Transformers action movie with low tech Indians doing the robot fighting it's got enough for that... Enough to suck horribly.
But yeah, I don't see it ending well if they tried to make a whole movie of far future robot dinosaurs. In fact, I think they could leave that out entirely, and make it all about Faro and Sobeck, and how Faro's arrogance led to the ending of the world, and that would be better.
