Just about everyone who knows about him says this but I think it was pretty fucked for Rache Bartmoss to exclusively be referenced as
Dead body in a freezer in a wasteland junk pile that Johnny (famously unreliable) identifies as being him (challenged in a vague manner by Pondsmith, somewhere on the internet)
A treasure hunt style quest that has you climbing up and down various structures in search of the 'Bartmoss Collective' that turns out to be nothing more thank a prank.
Rache Bartmoss, when he was alive, was a reclusive anti social (ish) freak first and foremost, but also one of the most brilliant independent minds of his generation. If they were going to turn the guy into a joke, they could have at least used the material that was already there... like how he went on one date with one girl ever (Kimi Tara) and swore dating off for the rest of his life. The man was a freak, but an important and well connected freak. I just hope one day there will be more about him that isn't vague.
