I was with you up until Final Fantasy XIII
Good topic idea. I would tighten it up by saying 'has feedback helped franchises? Which ones, and how?'
Note: Shigeru Miyamoto for ex once said he doesnt think feedback from the internet has any place in a game's design.
I don't like the business of tailoring games to feedback, to me it's the same process as releasing a teaser trailer like they did years ago for Tron Legacy, which had no script at the time, and then they FARMED opinion to the trailer to make a film that people THOUGHT they wanted to see, based on what they saw.
To me there's something if not uncreative, is just uninspired about working that way.
I think it's a great topic BTW
