I'll forever have a soft spot for the first video game I ever played after my baby hands learned to grip an N64 controller.
It's ancient now, but it's still got a charming "90s polygon" aesthetic to it, and an ethereal, almost dream-like atmosphere.
But outside of the few unlockables, and to see the series origins, there's not much of a reason to come back to it.

This is the game that introduced me to Metroid, F-Zero, Earthbound and Star Fox though, and I'll always be grateful for that.
