kathy this is so sweet what!!!! i really adore this idea. i wanted to do something similar, but i don't go out all that much, so i don't actually have much opportunity to use a pedometer. i really agree re: extra content for a meaty game; HGSS has so much stuff to it, it's definitely the Definitive version of johto to me!
ICanSnake munchlax with explosion is craaaazy!!!! i can hardly imagine a snorlax with explosion.
Sheep i can definitely understand! i was too obsessed with it to let it sit at home; i felt like i was leaving a pet at home when i could be taking it to school with me LOL. i'm sure whenever you dig it up it should function with a new battery!
tkarispe the distributed downloadable stuff was SO COOL. getting yellow forest from my local gamestop felt mind-blowing at the time. i remember hearing it was a pretty accurate pedometer compared to other contemporary pedometers, too, but i don't know how substantiated that is. at least compared to my digivice toy it was pretty accurate!
i feel the same way vis-a-vis pokemon go too. the adventure sync isn't quite the same. heck, the medium in which the game exists just isn't the same. it's not a dinky little add-on with an LED screen, it's a fully-featured game itself! but i still prefer the pokewalker's simplicity and novelty. and i don't need to connect to the internet. which is always a bonus for anything i use...
