I’m working on my tech level system and I decided to rearrange a couple of them. This is what I have now:TL 6: Pulp Age (1900 – 1945 CE) - This includes World War 1, the Roaring 20s, and World War 2.TL 7: Atomic Age (1945 – 1980 CE) - This includes the end of World War 2, the Cold War, and the Space Race.However I was thinking about splitting TL 6 into WW1 and having TL 7 cover WW2 and Korea since most of the technology of the Korean war was developed during and right after WW2. The TL 6 would still be Pulp Age but I don’t know what to call the new TL 7 that would encompass it. Maybe call it the Atomic Age and call TL 8 something else?Also I was wondering what people considered good year ranges for each of these time periods. I could see the Pulp Age starting even earlier than 1900. I’m not sure what year would be a good transition point between 6 and 7.Any thoughts?
