: Way back in the late aughts, I came across an essay someone had written
: breaking down the story of Marathon Infinity and walking step-by-step
: through its meaning and interpretations. With the new Marathon looming,
: I'm suddenly waxing nostalgic and would like to take another look at it.
: Has anyone seen it? It was a long form essay, I want to say... fourteen
: pages? It went very in-depth.
This seems to meet the criteria of your description, and I've never really seen anything outside of content on the story page that's as in depth about marathon as you're saying:
