Oh! It was when Sacred Stones was released...
I asked my mom for a new gba game, I wanted "Golden Sun", and she said that it was fine, so, when she returned from his job, she bought the game, but when she gave it to me... It wasn't Golden Sun! It was Fire Emblem Sacred Stones! And I asked her how she confunded the games, and she told me "I remembered that the game was related to fire" (because of "Sun") ... So I played my new game, and I loved it! Never played Golden Sun, but I played all the Fire Emblem from 6 onwards~
