Well, what idea did you have?

Fictional World, fictional peoples, all of that. If you need tech similarities think along the lines of 17th-18th century gear, supplies, and concepts. As player character's we're forced into a greater and massive area of unclaimed land thought too empty and barren by our homelands to feasibly survive. But our groups, acting independently, manage to come upon a land beyond the steppe wasteland and set down to establish their own society.

Disconnected from their homeland and its institutions they/we then must build our own institutions to serve whatever sort of ideology that our groups were otherwise exiled for. By pure need these groups will most likely have to adopt a sort of proto-socialist/pre-monetary economic system.

In short: no "Our World" past or future. I get the impression you didn't read my last post.
