I m in the process of creating a big catan version but laying out the main tiles I m wondering to proceed creating the border tiles as per original.it will probably make the island huge and possibly create extra overhead ( trading , components placement…) .I m considering just leaving the island as is and make custom ports with triangles to add around the board.
Also suggestions on the size of roads,sett,city are welcome.(I feel they are little too big)
