Giving this a shot, even though it's been several years since this challenge came out.
Used the sandbox settings.
Will be posting any cuties that are birthed or that I invite into my tribe.
Original rules:
here it is! ^^ it isn't too terribly different, but the starter has some more restricted genetics (so you can't get lucky and get off easy with horns for example) and the age stages are shorter, among other things. here's some optional rules that I like to play with: 1) never start on an easy island (you don't have to start on Grass Mingle if you don't want to, just not an Easy island) and 2) you can't attack predators (definitely makes it a challenge!). and of course, 3) no mutation menu!
