I'm the same way -- none of my peers in the real world understands my obsession with Chrono Trigger. Sometimes even I don't understand it, hahaha...
Chrono Trigger was my first RPG. I had two best friends growing up, and they were both playing it before I was and I remember one of them trying to describe it to me in a car on the way to a baseball game. He was specifically describing the domes of 2300AD and killer robots and all I could picture was a Mega Man-esque sidescroller with some Legend of Zelda II elements.
It sounded rad, so I begged my mom to rent it from the local Giant Eagle supermarket (which also rented movies and video games). She did, and I spent an entire night exploring 1000AD, before traveling to 600AD.
I've been in love with the game ever since.
My friends quickly moved on, and they never understood why I couldn't. I don't talk to them much anymore, but I saw one of them last year at a funeral. I told him I was still obsessed with Chrono Trigger -- 22 years later -- and all he could do was shake his head and laugh.
