Some other world I've thought of include:

The Roaring 20's

The Mainframe (A world based of the 90's. It's all pixelated n' stuff)

The Renaissance (kinda like a day Dark Ages w/ different stuff of course)

Discovery of America

Civil War

The "Cold" War (so Pepper-pult is used sometime after FBC)

And maaaaaaaybe one of the WWs
