In case my words and off screen footage of the Dragon Age: Inquisition E3 demo did nothing for you let me present you with the first half of said demo in video form. It is a bit different than the one I saw in the fact that the main role being played is a different class but hey, everything else is the same. That and now you don't have to read as many words to get the full experience of what was being shown behind semi-closed doors. Now you only have to wait for the video to buffer and not the hours of wait time to get in to see the demo.
Seeing as this is listed as part one of the Dragon Age: Inquisition demo I think it is safe to assume that there will be a part two here soon to fill out the second half of the full demo shown at E3. There was quite a bit more that they were able to expand upon in that half of the demo in terms of story and character development while this half only focuses on the combat and exploration of Dragon Age: Inquisition. I guess so you can pick and choose what aspects of the game you want to see.
I won't bore you with more words here as I already did that way back when I sat through the whole 35 minutes of Dragon Age: Inquisition the first time. That was from the perspective of the Rouge in the game and not a mage, so expect those differences.
