Not sure I'd agree with the sweeping comment about the series, but the first three installments are definitely a trio of the best fantasy novels ever written.
On that subject,
Dragon Age Origins began its development in 2003.
At the time, three of the so far five novels in ASOIAF were released, with an additional book coming during DAO's development.
A Game of Thrones(1996)
A Clash of Kings(1998/1999)
A Storm of Swords(2000)
A Feast for Crows(2005)
A Dance with Dragons(2011)
The Winds of Winter(being written at the moment)
A Dream of Spring(supposed final book in the series)
The first three novels were the best in the series. DAO had a hell of a lot of great inspiration to take from A Song of Ice and Fire, and you could feel it.
It kinda makes me sad now though. Back then, you had to have read the books to know the world of ASOIAF, which means if someone brought it up, you could count on them being somewhat knowledgeable on the subject matter.
Now however there's Game of Thrones the HBO series which while great(I enjoy it), has made its way into popular culture meaning there are those with only a passing fancy for it, or those who have only heard of it and thus make erroneous assumptions.
Its one of my pet peeves. Back during DAO development and even immediately after DAO's launch you could talk intricacies between it and ASOIAF. Nowadays its all about the series on television, and lets be honest- the show is not a perfect adaptation of the books.
Before I go off the rails,
I'm glad they're not trying to force darkness everywhere like they did in DA2. I feel like DAO handled it perfectly in that the world was dark(and full of terrors, ey) but you could still find happiness and even end the game in a happy way(with the potential to end up having a less than stellar ending too).
DA2 forced darkness on us in foolish ways and the ending was...yeah.
Inquisition I think had the right elements, but maybe they could've been presented better? Inquisition is still fresh in my mind, so I think I'd need more time before I really break down how it could've done things differently and if it even needed to.
I enjoyed Inq vastly more than DA2, anyway. Though I find myself unable to really compare my enjoyment of Inquisition and Origins. Perhaps they're so far apart or so different I just find myself incapable.
