Hi there, my name is JorgeGG and I live and work in Santiago de Chile. I came here by accident, and well just given some random ideas. Oh, I forgot to mention, since I'm more interest in Doomsday 1983, I was a teenager by that time.
Do your homework. Research and see how others write similar histories.
Plausibility is Key. Avoid or at least know the common cliches or tropes for the timeline your are writing. For example a) Napoleon comquering all of western Europe or a successful Russian Campaing, b) A successul Operation Sea Lion (don't even try this one)
Butterfly effect. This means there causes and effects linked. One POD (and just one significant POD) alters the rest like in billiards, pool, snooker (Well, like in any cue game)
Order events in chronological order (from above)
Depth or width in writing.
Details must be relevant to the story telling. For example if you have POD were Kennedy is not killed 1963, don't make list of US presidents from the 1789 onward. Start from Kennedy (1961-1965).
Don't get lost in details.
World building relevant to the ATL. Don't waste time explaining things that are the same in OTL.
If you can describe a language, person or country in one paragraph. Do it!!. Don't create pages that are one paragraph long.
Don't be afraid to re do things if you make mistakes or half-way thru have another idea of it.
. Have Fun and be open to criticism and questions.
Cromwell the Great - A previous TL that I have adopted. Done a major rework of it. A Type II - Hard/Soft Alternate History (see above: Sliding Scale of Alternate History Plausibility). Winner of the 2018 Stirling for Best Timeline of 2017
Of Lions and Falcons (formerly named Spain Divided) - A previous TL that I have adopted. Work in progress. A Type II - Hard/Soft Alternate History (see above: Sliding Scale of Alternate History Plausibility)
From Sea to Shining Sea (formerly named Communist-Controlled America) - in cooperation with Stepintime (Caretaker of the ATL). A Type III - Soft Alternate History (see above: Sliding Scale of Alternate History Plausibility)
If you have any suggestions of questions on the above timelines, refer them in their respective talk/discussion page.
