We were informed this scene occurs shortly after Commander Shepherd returns to Earth to face trial for his actions in Mass Effect 3, (implying that Vancouver is a major Alliance city). We’ll obviously know more once the game is released, but it appeared to us as though Vancouver and Seattle have grown into a single city, and Vancouver has spread across the strait from British Columbia to Vancouver island. The Coast Mountain range is visible in the distance, and Vancouver’s distinctive architecture is apparent, if futurified. And it was gorgeous. Which contrasted nicely with the bleak setting of Mass Effect, fully established by the dozens of Reapers descending on the burning city in the final invasion of Earth.
