I would agree, although I will point out that we might also be looking at previous titles with rose-tinted glasses. Companion banter in BG1 was very limited. In Mass Effect it was basically down to a few remarks in cutscenes or elevators. I do not recall much interaction between companions in DA, but there were a few dialogues for sure. *snip*
Dragon Age Origins didn't have much, but DA2 improved upon it and DA Inquisition had quite a lot companion banter and scenes between companions. ME1 and 2 also felt a bit short on that end, but ME3 and ME Andromeda improved upon it once again and there were a lot of banter and banter between our companions. Felt like they were truly alive, because they talked to each other and visited each other.
