Here’s a good idea. These RPG gaming tiles from Fat Dragon Games are now available on print-on-demand but they print two-sided and are coated so you can write on them with dry-erase marker and then wipe clean. The covering also means you can use clear tape to stick the tiles together to ensure your dungeon doesn’t fly around during heavy dice rolls or cat attacks.
Fat Dragon Games has discounted E-Z Titles: Medieval Ship.
Fat Dragon isn’t alone with a new tile range. DramaScape also offers PDF+Tile combos. They’ve reduced Power Room and Computer Room in price too.
One of the great things about these titles is that they stack together as many times as you want. You could design a table size dungeon if you want.
