An amazing journey. Even if the end stumbled slightly, the journey with Sheperd is one of the most satisfying in all of gaming.

It will be a game set in the past then.. as in andromeda, they are all long dead by now. And that is very sad.

The music perfectly married with the game, it tears at your heat strings as did the decisions you made that had lasting effects.

End of a game, trilogy, BioWare, last cry of a proper character/atmosphere focused single player they ever did (please don't mention DA:I; it's grindy MMO-like).

Great video, not the best ending

And still this song and soundtrack makes me sad, it really shows this was the end of the Mass Effect series.
How could they have ended it so stupidly tho?
There must be some kind of relationship between Mass Effects ending and Game of Thrones ended.
Because both endings made my eyes bleed with how stupid they were.
And yet Mass Effect is the best game series I’ve ever seen and Game of Thrones was the best TV series I’ve ever seen, yet both there endings freakin sucked.
How could you botch something handed to you on a silver platter, but yet both the people over Mass Effect and Game of Thrones did it.
I don’t think I’d ever hire either of them again.
