The Matrix was huge and unique – not other stories have been so convincing that we could be living in a simulation. It’s time for a new one.
Simulations (like what we could be living in) cannot be scripted, otherwise what is the point – you could just make a movie.
Yet guidance is likely there. You need to seed a simulation with something different to the last one, or it will play out precisely the same. You can seed it differently, or add randomness (even the weather would do), or you can orchestrate things for a few characters and watch the flow on effect. Like perhaps Jesus walking on water.
[OMG, what if weather, or even just clouds, is a purposeful randomising factor, the thing we find hard to perfectly predict, in our simulation?]
So, the movie. Two, three or probably four people are in different parts of the continent (or world) , and all have a bizarre series of events that send them towards the same place, somewhere they are inexplicitly drawn to.
When they get there, and get a glimpse of what is going on, and what they need to do (something in the realm of a boss battle), the movie ends, a set up for part 2 called Hung or Quartered.
