This was... unexpectedly painful. 
This is a troll teaser. They know everyone wants Shepard in Mass Effect Andromeda. But they released this clip basically giving every one the finger. Bioware strikes again with their not so subtle trolling.
While I do not believe this was trolling, quite the opposite, I think it was meant to be a touching goodbye to the fans, it did make me feel like I got trolled. I wish I could be as happy about this "teaser" as most people here, but it just pisses me off.
And the fact that they chose femShep made it so much worse... being reminded of everything I loved about Mass Effect being left behind.
I think I might find it easier to forget Shepard and move on if Bioware didn't keep on reminding us that we need to forget him / her. "This is Commander Shepard, signing off "... Just a little too on the nose for me.
Yeah, the E3 trailer was already quite reminiscent of Shepard (e.g., positioning of protagonist in the ship), and now literally Shepard talking to us. I'm not sure who's the person saying, "The best way to move our fanbase away from Shepard is MOARSHEPARD," but he/she needs to just stop.
This! Apparently the majority of people appreciates this tear-jerker video, but HOW am *I* supposed to get over Shepard and forget the Milky Way if they keep bringing it all up in such a manipulative way?!? Bioware won't stop scratching at this wound!
I'm a bit baffled the teaser is being received so well considering that it looks like a cheap fan video slapped together in an afternoon and features Shepard whom people either can't wait to leave behind or wish was still around... 
The released concept art that sort of looked like the Citadel, but not quite, is probably going to turn out to be of the interior of the ark. We're going to need a new hub, and since this game's setting is going to revolve around finding new homes, meaning there probably won't be any settled worlds or space stations at the start of the game, the Ark is probably going to be the game's main hub.
And apparently they'll make us remember the Milky Way every five minutes in the actual game too... *sigh*
This is going to be one painful gaming experience for me. I wish Andromeda would be an actual fresh start. Would be smarter too imo. People are either going to be reminded of a trilogy they liked better OR it's going to bring up memories of how much the ending ruined the trilogy. How is that good??
Please Bioware, either don't look back and try to sell us why we should care about Andromeda, or stay in the Milky Way. Currently they are doing neither in their promotion, and it annoys me.
That's my whiny post for today. Sorry.
