This is a false statement. The best Superman writers take inspiration from mythology. Guys like Brandon Sanderson, Brent Weeks, Stephen King, Patrick Rothfus, Robert Ludlum, all took and continue to take inspiration from other writers. That's why the two rulers for us writers (i am an author and a professional editor/writer) are: read and write. You cannot be a writer unless you read. And you read in order to take in inspiration and to build up your vocabulary. Man, can you imagine if doctors didn't pay attention to other practices within their field? They would still be using the same techniques that may have been outdated ages ago!
Storytelling wise, games are way behind novels. The authors I mentioned have written stories that trump dragon age lore by miles. They are the best at what they do. I love dragon age and mass effect and a lot of what Bioware has done. But if they stop thinking they can learn, then they cease to be useful at being creative storytellers. The gaming industry is in the midst of a change. The Witcher 3, and now it appears Fallout 4, are setting new heights for modern day RPGs. Need to keep pressing forward.
For one mister writer you don't need to take from anyone to write something of your own. Who the hell did the first scholars take from with nothing to read Huh? Yea no one. One can get inspiration from themselves. Pretty sure that the medical field and Writer field are two very different things.
Two ITS ITS A VERY HUGE CONSENSUS AMONG THE GAMING COMMUNITY THAT DA:O IS ONE FO THE BEST STORIES EVER TOLD THANK YOU.
As I said they don't need to take any ideas from anyone because they have already established themselves as one of the best story tellers in games standing toe to toe with Developers like Bethesda, CD, and others.
If you look back at the alpha we can see they can go out in a new direction but something obviously stopped them from going in that direction. What that is we don't know because they did not give us any answers as to why they did not give us what was shows and told to us.
Not saying they can't get inspiration here and there from something sure. Alot of writers do. But a lot of established writers don't need to either. They can get inspiration from within themselves and what they have already written. I anything the Alpha looked the witcher 3 before the witches was even out.
