I have a bunch too, but the collection started by accident.

I like Godzilla. I like the old movies, I like the new ones. He's a giant radioactive lizard, what's not to like? I'm not a superfan, but I enjoy the franchise(s).

I'm supposedly hard to buy for, I think mostly because my interests lie outside the rest of the my family's to an extent, and tend to be niche or technical in nature, so I get Godzilla swag and toys for Xmas and birthdays. I don't mind, it's fun.
