It's the latest show of creativity in the endless Pokemon life-sim.
I still remember where I was when I first heard the title theme for Pokemon Red and Blue. I'd just badgered my old man to take me to Toys R Us, where I grabbed my Blue Version, and before we'd even gotten into the car to drive home, it was in my Game Boy. The title theme hit just as we were leaving the car park and heading towards a giant bridge that serves as a bypass for my town. It's a foundational memory, and I have such a soft spot for the song (and Pokemon as a whole).
