“Favorite video game couple”
For me it’s really only a choice between two, and neither is from Final Fantasy. I really like Hiro and Lucia from Lunar: Eternal Blue; their romance was one of the things that made me start really caring about stories in video games.
But for my favorite, I have to say the main characters from what’s probably still the most mature video game story ever; Fei and Elly from Xenogears.
