I think the question is more like could a great team produce the next FIFA AND the next Call of Duty due to some kind of process improvement? I don't know, maybe there are hugely inefficient processes right now, but the sorcery of the art, to find 'the fun' of a new game concept or formula still feels very mysterious and ambiguous. Of course most games are just building on existing formulas of fun, but then you need a fresh edge to fight the established incumbent of the genre.

And if you found this secret process or meta formula for coming up with new amazing game formulas, why not just keep it to yourself to build the most spectacularly successful game studio in history. (Maybe that's Nintendo? Blizzard at its best also has some magic touch on any new genre they touch, even where they mess up like Overwatch they end up making and taking down the entire genre with them.)

I dunno, maybe in ten years game development will be like some automated AI windtunnel/R&D lab remixing various game genres and formulas and spitting out new fun things. But I like that there is a sorcery to it for now that elevates human creativity over process.

This is of course very true, genuine creation in video games is still and perhaps always will be (and indeed arguably we should hope it will remain?) an unsolved problem! I was just being somewhat snarky due to the parent seeming to wholly disregard the idea of assembly line video games when they are very much a feature of the landscape :P
