Completly identical, with exactly the same sensory inputs, no interaction between each other, ... ? Would be very hard to implement, and pointless, unless it's a safety measure to ensure you survive the accidental (or criminal) destruction of the physical support of one of the two simulations.
But the main problem I have with that is that you'll need to restrict the freedom of action of both those simulations if you want to be sure none ever affect the other. If I were to be part of simulation, I would like to retain an ability to affect the real world.Partly because I want to be aware of what could affect the physical support, and have an ability to act on it. And that would be very hard to achieve for both of us without having any of us interacting to each other and keeping us totally identical.

I don't see what the implementation difficulty would be. You just run exactly the same simulation on identical hardware and feed it identical inputs. There are technical issues, but they have known solutions: we already do this today. If the simulation requires random numbers, they just need to be duplicated as well.
Suppose I have choice between the following:
A) One simulation of me is run for me 100 years, before being deleted.
B) Two identical simulations of me are run for 100 years, before being deleted.
Is the second choice preferable to the first? Should I be willing to pay more to have multiple copies of me simulated, even if those copies will have the exact same experiences?
Forgive me if this question has been answered before. I have Googled to no avail.
