Pretty self-explanatory. Using whatever POD you need, make the world as technologically backward as possible.
Ground rules:
1. Homo sapiens are still the dominant species, and no other members of the Homo genus exist.
2. POD can be before the OTL rise of civilization. So you can delay agriculture, etc, if you want.
3. A well placed meteor shower is acceptable.
4. Bonus points if the world is pre-gunpowder in
2000.
5. No nuclear war.
I realize that the world would be unrecognizable, but that's what I want. Draw on your creative skills and make new empires.
