I think romance relationship in vanilla is pretty barren, nothing more than lovin', marriage, or breakup. The goal of this mod is to make vanilla romance more lively and flavorful. It adds a new "Romance" need and several romantic interactions, thoughts, and precepts.
1. New need: Romance:
Pawns who have lovers will feel good or bad based on its level; they can get it through (automatic) romantic interactions.
2. New "interactions"
When their romance need level is low, colonists will spend some time doing these kinds of romantic interactions:
If you really like or hate one of them, you can adjust their happening weights in mod settings. Set it to 0 will completely disable that kind of interaction.
3. New Thoughts:
4. Precepts (Ideology):
This mod adds four precepts that allow you to take more control over romance in your colony: Cheating, Romance attempt, Breakup, and Marriage proposal.
Generally, there're four options: Arranged (those four kinds of interactions will not triggered naturally, you can only execute it manually with right click.That doesn't mean it will 100% succeed, you can see the success chance if you activate it in mod settings.) Forbidden (simply set its prob to 0), Discouraged (halve its chance), and Encouraged (double its chance).
What's your view of love? Would you like nobody in your colony will marry or breakup? An Utopia where no one will cheat others?
