Gaiden is an episodic side story following The Lad in his search for The Kid/Guy. Why does The Lad seek The Kid? Who cares -- it's a 3 stage episodic bite of new IWBTG action. What about the future of Gaiden? Hard to say. Brave Earth is going to steal my attention until it's done, so don't expect more any time soon, but I surely will add more content at some point. How big will that content be? How many episodes will their be? Who cares, I'm playing it by ear.
