I guess because of the many modes of play of the game there can only be this type of mat? No way to have a campaign focused mat? Also, $20 ain't cheap...
The mat works for both versus and tall tales! 20$ is expensive...I didn't set the price but it's fairly standard I think for a plat mat. PLUS IT'll HAVE MY ART ON IT!
The expansion ALSO comes with 4 player mats. They are small and cardstock, but they have duel guidelines for both versus and tall tales, and they keep your character space organized.
So, by no means think of the neoprene mat as the only option for organization.
