:
I have seen a reference to Nolybab in the intro cinematic.
"Failure to demonstrate 'cake' status to Nolybab courts"
Not really an easter egg, but a nice reference. 
I really like all the in-universe references in NNT. |
I'd also like to point out one of the locales RuptureFarms services, according to that panel, is "Mongo". Very likely the Mongo Valley, as the little anecdote appears to say "Interest Following … Privatisation and Game Hunting", obviously a reference to Sekto establishing Sekto Springs, as well as the eradication of the Steefs. Very cool. I guess since Sekto moved in, the need for distribution of outlying franchise foods has diminished.
The second locale appears to be Necrum. The anecdote stating "…sets no one … lives here". Obviously, it's a desert.
