The problem with writing is basically nearly everyone thinks they are good at it (if they tried...). So why use someone else? Even after the dross is down on a piece of paper, it can still look great to the author. While game programming, or 3D modelling, is pretty obvious straight away if you are any good. And even if people slag off your writing, then you can still think they don't know what they are talking about. Not so easy comparing words (when you are as biased as hell) as with, say, a horrible red cube compared to fantastically rendered Orc from LOTR, for example.
Just my 2p. But I think I wrote it so well

I am 99% probably lying in bed right now... so don't blame me for crappy typing
