fact is guys, these two go hand in hand. art is truly a science. even creative writing is boiled down to simple equations. the only writers who do not have a high intellect never really get published. take tom clancy. he focused his education in the military aspect of the world and has made a career creatively writing stories that go with what he knows. remember also, the writer needs to possess every bit of knowledge that is in their books. this is accumulated from characters and other input from the story.
thats novel writing out of the way, lets look at video game writing. most think writers just pop in and start writing story lines and dialog. but in reality, most need to know how to code the dialog so the programmers don't have to rewrite everything, just copy and paste the file created by the writers into the game itself. This saves countless hours.
television and movie writing also follows a code. when you learn about screen writing, you find that a film is broken into different parts and each of these is broken into parts also. this is the reason we have predictability in films and television these days. the only films that stand out are those who are splendidly written or break this code in a way that the audience is pulled in through curiosity. generally, their just put off by the strange workings.
I am not saying that those who have creativity are intuitively smart, or that an intellectual person can write a novel. but a high basic balance is best for production.
