From the new post:
When I saw a picture of Dyack and him going on and on about Norse mythology, I said to myself, “How did he wander into this industry? He is supposed to be the typical failing writer!â€
That part made me laugh. It applies in more ways than the post even mentions, Dyack seems to love writing stories but the game is an afterthought, as if the game was showing a great movie and suddently interrupted, saying "Oh, hey, you there in front of the TV! We almost forgot about you, here's your assignment to be handed in until 3pm: Kill 12 zombies, 3 robots and 1 boss. Come back once you're finished."
I think the whole talk about pruning the parts you like for the customer made me develop a theory why Miyamoto is so brilliant:
He is not a gamer. In order to think like a normal person he doesn't have to make assumptions, studies or anything, he just looks at himself (didn't he say he also shows his ideas to his wife for approval?). That's probably the biggest difficulty other game designers have, they don't know what the average person wants, they can only guess. They write up a design without knowing if the customer wants it, then the requirements clash and in the end they either realize they made the wrong game or they think that's a good thing they did.
