The Elder Scrolls 5: Skyrim.
Speaking to Kotaku, Sarah Briody said that when her boyfriend, whom she introduced to Skyrim, offered her the amulet, she didn't recognize the significance right away. "I put it on and he started to smile from ear to ear. Then he said: 'Is that an Amulet of Mara? I'm surprised someone like you isn't spoken for.'" We hope he said it with a thick Nord accent. You know, for authenticity.
Briody's partner also proposed in the more traditional way, by kneeling and offering a ring. Briody posted images of the engagement ring and amulet on Reddit, where people promptly speculated that the couple met 10 minutes before their engagement, presumably after Briody's now-fiance fetched her a mammoth tusk.
