Sony is developing an MMOG called Free Realms, and simultaneously has licensed Topps to create a CCG to go along with it. The digital card game will launch with the online game, and the physical game will launch next spring.

The CCG will work in coordination with the online world, like similar recent CCGs based on MMOGs.

This will be the first foray by Topps into collectible card games, and its branching out is a result of its Acquisition last year by Micahel Eisner’s investment company, Tornante.
