Sometimes you create a game with moments that define the experience, and stick with players for years to come. Sometimes those moments become memes, and that's exactly what happened with the 'laughing' scene in Final Fantasy X. Now that a new generation is getting to expereicne that laughing moment in a new way with Final Fantasy X HD Remaster, Game Informer decided to ask Producer Yoshinori Kitase about his feelings on the way the scene is regarded nowadays.
Even in the real world, actions taken by two people in a budding romance are generally embarrassing memories when you look back on them. I believe that this scene depicts that mental state very well. This scene of course is still made fun of by fans, but I imagine that it is because it greatly touched “something” in everyone’s heart for it to be such a memorable scene even after 18 years.
