*** SEEDS FOR Alpha 19.0 Stable ***
Huh... I'd have to spend a lot of time here to do this. I have about 200 different seeds for alpha 19 experimental, half 4k and half 8k. I have previews from all of them publicly available here: https://www.dropbox.com/sh/ljjksykyenytm3e/AAAh0mf_CBnXW92eVl5i-EF1a?dl=0
To generate and analyse these seeds I use scripts that are freely available here: https://github.com/dcsobral/seedGen
All my 8k seeds have 10 traders, all my 4k seeds have 5 traders. To make it easy to figure out what seed you find interesting, I've added some of my analysis to a Google Spreadsheet anyone can look at. You can see the number of prefabs in the map, the number of unique prefabs, and the number of unique prefabs that are tier 4, tier 5, stores, skyscrapers or in my top 7 and top 15 lists. Once you find a seed you like, go to the drop link above, download the zip file, and you'll find a map preview there. Traders are marked in the map previews with pinkish outlines, though you might have to zoom in to spot it.
I also have a thumbnail preview of all seeds, with color coded buildings. Legend for the seed previews here: https://imgur.com/m1FatgC
