I guess it depends on how high a level you're looking at it from. Both lockstep and rollback are variants of the general approach of "shared deterministic simulation" where you're mostly just sending inputs. ("Mostly" 'cuz on reconnect or desync or whatever you'll probably want to send full state.) I really enjoyed this GDC talk on rollback networking: https://www.youtube.com/watch?v=7jb0FOcImdg&t=536s https://www.youtube.com/watch?v=7jb0FOcImdg&t=536s (From 2019.)
