Which settings make a better "Snaky Continents" map?

Fractal with high sea level, Island Plates with low sea level, or Archipelago with low sea level?

 

Don't know, but you might ask in the mod forum or on steam. I suspect it will probably be determined by the random number chosen to create the game. It might be one of the digits or a pair that determines the shape. You could try experimenting with that random number.

 

Get the Detailed Worlds mod on Steam and try their Archipelago map setting. I just played a game that way and had some excellent snaky continents.

 

Even Fractal with High Seas always produces a Pangea. I don't know what's wrong with fractal, since it worked perfectly fine in Four and Five, but...

 

I don't know one way or the other, but it wouldn't surprise me if the code for map generation in Civ 6 needed to be written from scratch, i.e. couldn't carry forward what worked in prior versions of the game.

 

I would really like a map type like continents but with some medium-large isles spread around so one could colonize. Those isles could have more resources than usual too to encourage colonization.

 

You mean like the Terra map script in Civ V?

It's not officially in Civ VI, but there's a mod that adds that feature.

 

I'd really like a map like this. Plus if you go for Cartography early you'd be rewarded with getting the first cities on those isles.
