At some point everything seemed to use Havok, due to that I personally don’t really have a strong association between Havok and Bethesda games in specific. Just take a look at this (incomplete) list: https://en.m.wikipedia.org/wiki/Category:Video_games_using_Havok.

Your comment does make me wonder if the Oblivion remaster kept the Bethesda physics jank, Oblivion wouldn’t be the same if clutter on the table doesn’t start flying the moment you pick up a fork. 😂
