Thanks everyone. Buildings, as mentioned in previous Super-posts, are Fat Dragon pdfs. Print and glued to foam core. They're nice, as the pdfs have layers you can turn on or off. Want more cluttered streets, you can turn that layer on before printing.
Thanks to Photoshop, I can go even further and add color to the buildings, getting more variations. I could, if needed fill my 8x6 table.
I'm working on a really stripped down set of rules to pack the table with heroes and villains in a huge "Secret Wars" type battle.
