Using my own PERL scripts to generate the world as fully tiled, thus donut-world. Scripts create everything from topology to final game map. Previously released here: https://john.gregorek.com/Games/Generic.zip
The README.dat lists the scripts in order of operation and ends with a PERL primer.
Still testing CRETACEOUS, a follow up to JURASSIC. The scripts will get uploaded again. A few additions that will be useful to any map like fading relief-tiles. The primary change is to generic_pl which now produces CRETACEOUS, complete with triggers and other useful examples for anyone to carve up.
The scripts are proving very useful in creating new topology so that the game doesn't get old. The only human part is selecting kingdom locations. A few minutes later and a completely new CRETACEOUS map is made. I am particularly proud of how the bubbler turned out (follows the topology to make the territories).
