The full release of farming sim Fields of Mistria has introduced marriage, letting players wed any of 12 NPCs regardless of gender, alongside the ability to start a family, features that were absent from the earlier early-access version. The addition marks a significant expansion of the game's relationship mechanics, giving players a clearer long-term goal beyond farming and exploration.

To marry, players must raise a character's Love Points by gifting items they like, reaching eight points to unlock dating and completing that character's Heart quests, before filling the Friendship Gauge to its maximum of ten. At that point, players can obtain an engagement ring recipe from the NPC Elsie, craft the ring and present it to their chosen partner to trigger a wedding cutscene; unlike romance, marriage can only be with one person at a time, though married couples gain perks including the option to have children.
