I've been seeing your posts lately about the PS2 games you've acquired, and now this one! I really like them! You're talking about games, showing a different side and using physical materials in a world where 90% of things are code!
It's great how game universes expand into literary processes. I'm currently playing Death Stranding and I want to read its novel; the same thing happened to me when I played Metro 2033!
Mass Effects definitely has a very good plot.
