The buddy system
is Pokémon Go’s latest cloying grab at my ‘90s kid nostalgia. Think about it: you, your favorite Pokémon, together, walking, forever into the sunset; growing as one and traversing the unknown. It’s just like Ash’s journey in the Pokémon TV show, except if you’re attempting it with the IRL buddy system, you might realize halfway through that your legs have become bloody stumps.
