Anyway, all of the pitches sound interesting. I think telling an AU story of us all trying to become Elden Lord following the shattering makes sense - though perhaps setting it earlier within the timeline, to where the Erdtree was still standing tall and the roundtable hold was in it's prime.
AU set earlier could be interesting. Maybe the game is the story of the previous generation of Elden-seekers, who fuck it up so hard that they become the reason the Erdtree closes itself off to the Tarnished in the game proper?
Separately I like the idea of an AU Shattering, each portraying Demigods in the early days almost immediately after the cataclysm, with various particular political alignments and power-gatherings etc in time for an all-out-war.
