How about more Post-Apocalyptic content and possibly a world?
For examples of design style and Sims take a look at the Post-Apocalyptic Murkland: The Starter Challenge
created and presented by @Brennachan
Look for #Murkland in the gallery for a fascinating array of households and lots.
Steam punk themes and very basic run-down, worn, tattered content.
Of course all the City Living and Vampire content has faded wallpapers along with rips and tears and spider webs work as long as you own those packs.
