There’s an interesting article on the UK Games Workshop site – a photo essay of the construction of the large Cities of Death table featured on both the site and in the CoD rulebook.
With an inexhaustable supply of CoD sprues in their hands it’s no surprise the table looks great, but I did find it interesting how they went about prototyping it with full scale cardboard buildings before actually committing anything to foam card and plastic.
Using different heights of ‘riser’ for the various city blocks also adds gaming opportunities, which is something I learned first hand when constructing my own Mordheim table.
