My proof that it was a Bethesda game was when I was first exploring New Atlantis, and I tried to talk to a man who was relaxing at a table in a bar. He instantly snapped from his relaxed pose into a different animation where he slowly got up out of the chair, turned around to face away from the chair, stopped, turned to face me, then the camera zoomed in on his face and he spouted some random TMI opening sentence about his job.
I just cackled and cackled for a good 5 seconds or so. Feels like home.
