Mario is a king but Princess Peach appears to be a bishop, and Luigi is the queen. Perhaps there’s more to Mario and Luigi’s relationship than we realize. Anyway, this Super Mario chess set would be a big hit with video gamers or fans of the game of chess. The game pieces are hand painted figurines from the Mario-verse, worthy of display in any toy collection, and the set comes in a nice metal tin. It’s great for getting kids interested in playing chess, but there are certainly many adults who would get a kick out of this.
