Does Steam push big titles to be exclusive, or are games exclusive to steam because they don't have a market need to also be on EGS?

To the second line, systems with a network effect tend to clump people together.

Yeah, I can't think of any explicitly Steam-exclusive games off the top of my head, other than maybe Valve's own titles.

Given Steam's history and market position, they don't need exclusives at this point. I do remember the likes of Outer Wilds and Final Fantasy 7 Remake being EGS exclusives for the first year of their respective PC releases.
