So you know what Bioware made their name on? They made their name on the fact that their games come with the capacity for the player to make real, morally grey, difficult choices, that can completely alter the course of your game, and how the story unfolds in response. So of course, given that, it does make sense that Bioware will play up the potential for choices, and the impact that they can have on your game, when they are promoting and marketing their titles. And in the newest trailer for Dragon Age: Inquisition, that is exactly what they have done.
The trailer above shows you the devastating impact of wrong choices in the Dragon Age world, and it even includes a special appearance from Hawke, the champion of Kirkwall who was the hero of Dragon Age II.
Inquisition, meanwhile, launches on Xbox 360, Xbox One, PS3, PS4, and PC on November 18.
