25. A method performed by a computer system to simulate a physical event, the method comprising: receiving a first input of one or more attributes related to a physical context of the physical event, wherein the receiving the first input of the one or more attributes includes receiving at least one first attribute related to a present location of a physical entity in the physical event; receiving a second input of one or more parameters related to a prediction of future behavior of the physical entity, wherein the receiving the second input of the one or more parameters includes receiving at least one parameter related to information usable to predict the future behavior of the physical entity in the physical event, wherein the at least one parameter is received in response to the at least one first attribute being presented, as a stimulus for the future behavior, on a display; receiving an indication to activate a computer device to start a simulation of the physical event in a virtual context in which the physical entity is simulated, wherein the start of the simulation includes positioning the simulated physical entity in the simulation at a location that corresponds to the present location of the physical entity in the physical event in accordance with the at least one parameter and in accordance with the at least one first attribute; and in response to receipt of the indication, starting the simulation with user control of the simulated physical entity to interact with the simulation from the location at which the simulated physical entity is positioned.
29. The method of claim 25 , further comprising receiving at least one second attribute related to an actual present occurrence in a physical context other than the physical event, wherein the future behavior of the physical entity is stimulated by the at least one second attribute.
