Game: Reiner Knizia's Callisto

If you've never heard of Reiner Knizia, you really should take a moment to look him up. Claims that he's "the world's most accomplished game inventor" seem pretty reasonable; after all, the man has created over 500 published games (most of which are pretty highly regarded within the board/card game communities). That said, many of these games have yet to be ported to digital platforms. However, based on Reiner Knizia's Callisto, more of these games deserve such releases.
