>>52831958Pokemon aims to create the experience of owning an animal, a pet. This is something they've talked about in the past and as to why starters are based off animals popular with children since they want the first Pokemon to be a familiar one. Again at it's core Pokemon is pretty much about interacting with magical critters and this is how the series is constructed from the start. Pokémon act the way they do in the domestic and wild sphere because they're meant to mirror real critters from the real world except fantastical.
