SIMULATION DEVICE, SIMULATION METHOD, PROGRAM, AND INFORMATION STORAGE MEDIUM

First control means of a simulation device simulates motions of a plurality of virtual players that are placed in a virtual world and other than an operation target of a user. Determining means determines whether a situation of a game being simulated in the virtual world is similar to a situation indicated in data. In a case where it is determined that the situation of the game in the virtual world is similar to the situation indicated in the data, second control means controls, in place of the first control means, the virtual players other than the operation target of the user based on a motion associated with the situation.
