<div>In this paper, a direct general specification for simulating an entire
universe would be given. The simulation would be targeted as same as
maximally having physical considerations in reality.</div>


<div>Background: By identifying the universal attributes of basic attributes
in an universe, scientific proposition of creating simulated universe
could be derived.</div>


<div>Methods: By extending the Monty Hall Problem derived from the result of
P vs NP Problem and Game Theory to the understanding of a single
observation, the continuum of total observation events creates a
distribution of probability which could be translated into distribution
of possibility. And using from what has been defined in this universe,
methods of utilizing simulation of reality could be described.</div>


<div>Results: Technical specification for creating axiomatic universe in
existing universe could be described.</div>


<div>Conclusions: In generalized terms, simulated universe could exist with a
customized reality.</div>
