A modder with the nickname murrayj decided to diversify the romances in The Elder Scrolls 5: Skyrim with an unusual mechanic. He took it from Dragon's Dogma 2, known for its variability of NPC behavior.
A mod with the simple name Dragon's Dogma 2 Blushing makes romanceable characters blush embarrassedly when meeting the Dovahkiin. The blush will be brighter, the higher the relationship level with them. By default, the effect will only appear for those NPCs with whom the relationship rank has reached 2.

Another unusual mod was previously released for Skyrim, literally mirroring the entire game. And recently, a digital artist transferred the city of Riften to the Unreal Engine 5, making it a real trading capital.
