1. A method performed by a computer system that has a processor and a memory to simulate a physical sports event, the method comprising: receiving, from the physical sports event, one or more attributes that correspond to participation of a physical sports player in the physical sports event, wherein the one or more attributes include at least one attribute related to an actual present occurrence during the physical sports event, and wherein the at least one attribute includes location information that corresponds to a present location of the physical sports player during the participation in the physical sports event; receiving one or more parameters that include information usable to predict future behavior of the physical sports player, wherein the one or more parameters are received in response to the at least one attribute being presented, as a stimulus for the future behavior, on a display; starting a simulation of the physical sports event in a virtual context, in which physical entities in the physical sports event are simulated from a situation similar to that of the physical sports event at a time of the start of the simulation, wherein the physical entities include the physical sports player, and wherein a simulation of the physical sports player is based, at least in part, on the one or more parameters, the location information that corresponds to the present location of the physical sports player, and the predicted future behavior of the physical sports player that participates in the physical sports event; enabling participatory user control of the simulated physical sports player in the simulation of the physical sports event; enabling control of an action by at least one of the simulated physical entities, other than the simulated physical sports player, in the simulation of the physical sports event; and controlling the simulation of the physical sports event with the simulated physical sports player under the participatory user control in accordance with the predicted future behavior, and with the controlled action by the at least one of the simulated physical entities other than the simulated physical sports player.
