Here are some good references for abandoned places

Although it's only a couple years old, this town abandoned as a result of the Fukushima nuclear accident shows how things can be when they're suddenly abandoned. Stores still full of merchandise, vending machines stocked, but other things (like buildings) damaged or falling apart. Imagine what this place would be like if it were left alone for 30-50 years.

Also, a quick update: more Tribe 8 content is coming, and once I get past a couple milestones in working on Apotheosis Drive Exodus I will be returning to the Fate Core conversion. Also, I will be reviewing the Spark  rpg on Aggregate Cognizance in the next week with an eye toward adapting Tribe 8 to that as well.
