I love the idea of going on a country-wide journey without having to pay for hotels/meals etc. All of the fun, none of the dull and expensive planning.
Also, you can leave home at ten years old and travel alone, and never have to worry about being raped/mugged, and everyone everywhere will be nice to you (barring the designated evil team who you can just stomp flat with you new best friends).
Pretty much this. I'd love to live in the Pokémon world, it's so safe and idyllic. I'd also love the big cities (Jubilife, Castelia, Nimbasa) to be real. They're so breathtakingly beautiful and to see them firsthand would be amazing.
