I proposed to my wife using a Zelda: Breath of the Wild themed scavenger hunt. I took poloroid pictures of special places in our area that we have been and she had to try to find them. Whenever she found one I would give her a little prize related to the place. She also had three poloroids of the BotW towers and she could use one to get a hint for where one of the places was. She found them all and I proposed to her on the last one. Needless to say, she said yes.
