After a thought-provoking post on the RPGsite and in the glow of my new Christmas tree, I put together a quick set of universal tables for randomly building city blocks. With a little work, they should serve equally well with most science fiction, science fantasy, or cyberpunk RPGs. Populating the blocks is up to you, depending on what your campaign style is. If you want a rough-and-tumble gang-controlled sprawl, take a look at my Wild in the Streets.pdf for some suggestions. Anyways, enjoy and comments are welcome!
