Since they keep bringing up the Warden, Hawke, and now the Inquisitor in the games, I have a feeling that it would be TOTALLY cool for DA4 to basically be like this:
A chapter where you play as the Warden, desperately trying to find a cure for the Blight while also amassing a power house of allies to help you as shit hits the fan
A chapter where you play as Hawke, combing through the fade, blades drawn and ready, furiously trying to find a way out, amassing a power house of spirit allies to help you find your way to freedom
A chapter where you play as the Inquisitor, trying to maintain power and balance as you desperately try to find peaceful solutions to the problems that are tearing Tedas apart at the seams, trying to maintain allies as you start to make shadier and shadier decisions in the name of peace
A chapter where you play as a Tevinter slave that starts an uprising, amassing allies and gaining enemies as you try to free your people from the clutches of evil once and for all, everything culminating into a big crescendo as they all come together in the end for the common good
AND THEN SOLAS IN THE BACKGROUND ACCIDENTALLY FUCKING EVERYTHING UP.
