I think sequence breaking is fun, and it works better in open world games. IME many modern open world games avoid this by tightly tying loot to levels or stats that you increase by leveling or even advancing the main story, which kinda defeats the point of open world games IMO.
Though honestly, I do enjoy having at least an illusion of choice, very linear games that don't even maintain an illusion of openness feel really restricting to me. Modern open world RPGs just took it way too far while getting some of the important details wrong.
