The biggest different between print runs is going to be the tokens. The first edition had varnished, engraved tokens and the Reprint (2nd printing) will have silk-screen ruler tokens. This change is for usability, as the silk screen tokens will be more easily recognizable across the table, as well as for practicality as the bulk of our missing part orders from the first print run were because the tokens. A silk screen print will make them stand out much better on the table. They will be the same size as the first printing.
The replacement tokens will come with a few updated cards that have fixed typos as well as a couple Wakhan Reference cards for Ricky Royal's FAQ and Errata.
