Either I'm missing something or it isn't interesting. If you aren't a Sim, you get 1 for Sim and .9 for not Sim. So your best play is Sim. If you are a Sim, you get .2 for Sim and .1 for not Sim, so your best play is Sim. Regardless of the piece of information you lack, your best play is Sim.

If you decide not to press "sim", you know that there are no simulations. It's impossible for there to be an original who presses "sim" only for the simulations to make different decisions. You're the original and will leave with 0.9.

If you decide to press "sim", you know that there are 1000 simulations. You've only got a 1 in 1001 chance of being the original. Your expected utility for pressing the button is slightly more than 0.2.
