There must have been a moment at the beginning, where we could have said no. Somehow we missed it. Well, we'll know better next time.
The only game that came with a playmat before Vegas was Wits & Wagers Deluxe. That playmat is replicated on the back of the Vegas playmat.
So you're essentially getting each edition of Wits & Wagers with what you pledged for.
I have the original Wits & Wagers, I don't think it's a "Deluxe" edition, but it has a playmat.
