ColdMC's overworld features Realistic Villagers! It greatly extends the functionality of villagers by adding interaction, marriage, children genetics, and more!
By interacting with the villagers your reputation will increase. When you reach X reputation, you can give them a wedding ring to get married. Once married, you can procreate, establish the home where the villager will live and even manage their combat targets. Giving gifts is the best way to raise reputation. If you want to divorce a villager, you can do so within the main GUI, but this will reduce a large amount of reputation. To avoid this, you can ask the cleric villager for divorce papers. You can give as a gift a weapon (sword/axe/bow/crossbow) and they'll use it to defend themselves when necessary, the same with armor. This makes raids more entertaining.
