The Next Mass Effect Teaser Trailer - Fully Examined

BioWare has released a trailer for the next Mass Effect game. So I decided to pull it apart and examine every quick scene and audio clip. Who is in the game? When is it set? What is the backstory? I think I've got some good answers for you.

Notes on Minius GC:
I originally was going to wait for the Mass Effect Legacy collection then do a single, long series breaking down exactly what happened with everything related to the franchise. Things were stagnant, but BioWare obviously has other plans.
However I am sticking to my plan. The intended, and previously unannounced, 'State of Mass Effect' video series should contain the most polished, in depth and complicated videos I ever attempt. That series also won't come out for a while. I want the elite 4k footage. I also need a PC that can handle 4k editing. The first of those needs the remaster to actually come out. Then I need to capture it, and dissect it and polish it . . . and so on.
Like I said this will take a while and isn't entirely up to me. For now check out the podcasts (I know they're not for everyone but I enjoy them).
Moving forward with additional content requires a reasonable amount of interest and I'm not sure that's there. We'll find out in the coming months . . .
