I read a thread recently about someone embarking on an island, which sounded pretty neat, so I set off myself with the idea of trying to generate a world with an island on it small enough to fit the entire embark site on (IE visible water on all 4 sides of the embark).

So far I've managed one world with an island that fits into a 15X15 embark.  I'm thinking it might not be all that bad, given that I won't have invasions and goblinite bringing down my FPS, not to mention lack of migrants.

But I'm wondering if anyone has any ideas for world gens that might increase the number of small islands and give a better shot at a smaller embark.  So far I'm mostly increasing the erosion cycle count, with the hopes of causing big islands to dissolve into small ones during world gen.  I've also pumped up a few of the river related variables (afraid I don't remember which).  I've gone back and forth with full/partial edge oceans, but it doesn't really seem to increase the total amount of water that much - I just end up with less lakes/inner oceans when I do so.

I'm thinking it'd be too small on the overall world map, so you'd need to browse the ocean tiles for one.

I'm thinking it'd be too small on the overall world map, so you'd need to browse the ocean tiles for one.

If you export a detailed map, each pixel represents one tile in the 16x16 embark area, allowing you to find the islands easier.

I was thinking the same thing, and had been time-consumedly browsing across each 16X16 area on the embark screen.  Exporting sounds like it would make a lot more sense.  Will try that with a few, thanks!

Edit: well, so far still no luck, but it's a lot easier to scout a map now at least.  I'm wondering if there is some process in world gen that wipes the island off if it shrinks to a certain size.

Also trying increasing the Elevation X and Y var, in hopes that it will create some island patches with high elevation next to low and the low will get eroded away, leaving the high patches as the new island.  But not having a 100% handle on world gen, I don't know if that logic is sound.

You could always use the guide I posted a while back.

How To Generate Small Islands, A Guide

It's a bit time consuming but more reliable than looking off the coast in normally generated maps.

If the ocean near your island freezes over, you can still get migrants/caravans/intruders.
