Both of you have misread the original post. Nowhere has OP talked about a single "correct" path, they've presented several "or" based transition options. You're straw manning this whole thread into something it isn't.
The OP's examples that provide a full pathway:
- Rome -> one of a series of acceptable intermediates -> Italy
- Greece -> Byzantium (or an incredibly obscure 2nd choice) -> Modern Greece
- Turks -> Ottomans -> Turkey
- Israelites -> Venice (???) -> Israel
- Aztec -> Michica -> Mexico
These are all clearly based off of reconstructing a pathway for a modern day construct of a national identity, and/or nonsensical (I am baffled by proto-american olmecs into the USA). They explicitly say:
The Last piece of the puzzle is to
1: RESTRICT every Civ swap to its NATURAL succession.
Leave the option to swap completely a civ to another, and maybe add a middle ground option, like shared borders, cultural exchange, but to ADD only Strict cultural proximity jumping, requires that all civs has a LINEAR optional choice in the first place...
2: RESTRICT Leaders to their Natural civilization. (And leave UNRESTRICTED Leaders as an option (as it was in Civ IV)).
3: Balance out the Age Reset and the tech reset... it is ok IMO if some civs still had to learn Writing in the MODERN AGE but had already unlocked Metallurgy....
but don't just plain the field at every reset as a Tech tree option for every civ should also get in a possible super-patch.
That each Civ should only be able to swap to its natural successor - i.e. to strictly build unique, 'correct' pathways to arrive at modern-day national state's national identities. I am not strawmanning anything, this is literally what the OP says - though they do say "maybe" there should be an option for "strict cultural proximity jumping", but only so long as those nationalist cultural identity pathways are created for all civs. They are very clearly insistent that this is supposed to create a clear, linear, correct option from which deviation might be acceptable. This thread has been, from the beginning, about creating pathways that justify identities only built in the last ~200 years, and which were built for political purposes, not for historical inaccuracy. That's what this is all about.
