The best way to deal with some of the hurt:
- DA2 - caves, impact on the world
- ME3 - red/green/blue
- bla - bla - bla
Is to get review copies into the hands of reviewers - a wide range of people, so not just the usual suspects and the IGNs...
And including some who mainly play Battlefield 4 or don't touch RPG normally (even the one who did the annoying 'Da Bears' footage)
Then give them enough time to play the game - including the ending.
Shadow of Mordor hit gold by getting copies out early and having the hype build that way.
BioWare do have a point to prove and this will help them prove it.
(I'm looking forward to Angry Joe's review - I like those)
