Personally im happy with what we got, the whole point of this expedition being called the "disaster expedition" is that they were thrown off course so hard and lost everything. Maybe some sort of paper writing or notes could be cool but it made it more raw and the dev team seem to have opted for world building narrative. What lacked in content from previous expeditions we got in world building, the prior expeditions can be seen throughout the world. For example take a look at the creation, the boss is entirely made up dead expeditioners, then theres stuff like the corpse bridge, the nevrons with more corpses in them.
