I have .modpack files for both - these are version 2.6. Working on updating to version 3.0.
The dino ruleset is based mostly on the experimental ruleset with some things from the civ2civ3 ruleset, including the variable city radius and new unit class "Big Land". Also has wild animals, plague, disasters, culture victory and my own tweaks.
The dino2 ruleset is based on the dino ruleset with some things added from the mp2 ruleset - government types Fundamentalism, Communism changed for better balance, new wonders added, new terrain alterations Fort, Canal and Naval Base, and many new units added.
Contribute, display and discuss rulesets and modpacks for use in Freeciv here.
