It's just perfect. The quiet beginning, the dialogue, the music, the scenes they picked.... everything.
The trailer completely encapsulates what ME2 is about. You can feel the game while watching it. You can know what it's about and know the impact it can have. In terms of Launch Trailer, you can't do any better than that.
I remember gametrailers made a list of the best 100 trailers a long time ago, and this got second place in the user vote, so I'm not alone is loving it. And I've seen many people since mentioning it as a top tier trailer. What do you think about it?
Anyway, happy birthday Mass Effect 2, the most special game in my life.
