Think of the possibilities of more interesting places to battle
My buddy Chris has these for us to use sometime whenever we feel like visiting Japan.
He also has the kit for this and still has to build and paint it.
Then he also has this kit that he assembled and still has to paint for some underground dungeon crawls, specifically for The Breeding Pits campaign for Frostgrave.
Just the tip of the iceberg of the possibilities for hexless gaming. Just like this is the golden age of boardgames, it's also huge for tabletop gaming as well, because there are so many great terrain options out there and the number of companies that make them keep growing.
