I made 2 different mods that can be played together and add new Factions to the game, using Xenotypes from Biotech, and no additional mods needed. It's very clean, and should be 99% compatible with all mods out there.

1940 Alternative utopic nations with French, German, Russian, Americans, Japanese, Spanish, English and Italian.
All of it quite clean and should be compatible with 99% of mods out there. It uses standard Xenotypes to add some specialties.

Fantastic races with Wood Elves, Dwarves, Dark Elves, Moon Elves, Goblins, Nekos and Draks.
All of it quite clean and should be compatible with 99% of mods out there. It uses custom Xenotypes for the races.
