A simulation system includes a processor including hardware. The processor performs an information acquisition process of acquiring user information including at least one of position information, direction information, and posture information of a user, a virtual space setting process of setting a virtual space, a moving body process of moving a user character corresponding to the user in the virtual space, a game process that is a process for a game in the virtual space, and a display process of generating an image in the virtual space as a display image to be displayed for the user. In the game process, the processor determines whether the user has made an item acquisition motion based on the user information, and upon determination that the user has made the item acquisition motion, performs a process of causing the user character to acquire an item.
