I don't follow or watch Mr Beast videos, but from what I've seen, they are largely driven by a money fetish and as far as "creativity", it feels on par with the more boring "What would you rather" conversations I had in middle school.
Maybe he has unlocked the key to virality by vigorously analyzing data, but looking at his videos, at a glance, it seems to more be formulaic, predictable, and simply having an actual budget that sets it apart (if it is actually set apart, as I find it hard to tell how much of it is others copying his work versus hius work being unoriginal).
His huge budgets and willingness to reinvest all the profits into future videos have allowed MrBeast to produce a lot of unique videos which are effectively unmatched by anyone else. Right now they're really the undisputed kings of the platform, by a massive margin.
