Objectives, an environment, and/or a theme associated with a virtual space may be managed based on characters made accessible responsive to corresponding tokens being detected. Tokens, including a first token associated with a first character or a second token associated with a second character, may be detected based on signals received from one or more token readers. The first character may be made accessible in the virtual space responsive to the first token being detected and the second character may be made accessible in the virtual space responsive to the second token being detected. Responsive to one or both of the first token being detected or the second token being detected, a given objective associated with the virtual space may be effectuated in the virtual space, an environment of the virtual space may be modified, and/or a theme of the virtual space being modified.
