Ah but that cutting and crafting comes WAY before any sort of public exposure in all those other mediums. If you see a trailer, the films already been made. If you see a piece of theatre (unless it's a workshop) then it's the finished product that has been cut and crafted for anywhere between a few weeks and potentially years. If I saw a trailer for a film and it had 70 foot trolls in it but then in the film there was no mention or showing of these trolls, and the filmmaker gave NO comment or justification for this: people would be ****** off and they'd have every right to be.
If stephen King gave an in depth interview about his upcoming book and said it was going to be about a space mole called Gary, and then the book rolls around, people buy it and there is no mention or showing of a space mole called Gary and is instead about something completely different....but he gave no justification or explanation for this.
People would have questions, and rightly so.
But apparently this is ok in video games.
It's not.
And you writing it off as "just part of the artistic process" is also wrong and doing yourself an utter disservice.
Actually you'll find a lot of shots which are in movie trailers are actually cut from films, it happens all of the time, or even if not cut entirely then changed and a different version was in the film.
Also the entire point is sort of a choice rather then ethics.
The game wasn't ready a year and a half ago, they work working on things which may not have been included? So it was a choice for bioware. Show content which may not make it into the game (and be very for front at the time that what you are seeing is in no way definatly going to make it into the final cut (which they were), or they could just keep quiet and not show anything until the trailers.
Now I think if you asked any fan a year ago what they would rather, at least 75% would probably say they want to see stuff as soon as possible.
So no I don't think it is an ethically 'bad thing' they did. All they did was open up the creative process to fans. They didn't show the fan the game that they were going to get, they showed the fans the game that they were working on, something which is subject to change. This would have only been unethical if biware never said that it was subject to change
