1. A system configured to manage a theme of a virtual space based on characters made accessible responsive to corresponding tokens being detected, the system comprising: one or more hardware processors configured by machine-readable instructions to: implement the virtual space to determine views of the virtual space; detect tokens based on signals received from one or more token readers, a given token being a standalone physical object, the tokens including a first token associated with a first character and a second token associated with a second character, the first character being one of a first plurality of characters associated with a first theme and the second character being one of a second plurality of characters associated with a second theme, the first token being detectable based on a first signal conveying information associated with the first token, the second token being detectable based on a second signal conveying information associated with the second token, the first character being accessible in the virtual space responsive to the first token being detected and the second character being accessible in the virtual space responsive to the second token being detected; and manage a theme of the virtual space, the theme of the virtual space being a unifying subject associated with the virtual space, the theme of the virtual space being modified based on the first theme responsive to the first token being detected, the theme of the virtual space being modified based on the second theme responsive to the second token being detected, wherein virtual space content associated with the theme of the virtual space is stored at a location other than one or more the tokens.
