>>33821316I was just exploring it fully for the first time (usually just skip past) and it does have a nice amount of variety in its layout and geography. Going by regions I would choose:
>Kanto Route 17 (Cycling Road) or 24/25 (Behind Cerulean)
>Johto Route 42 (Ecruteak to Mahogany) or 47/48 (Behind Cianwood to the Safari Zone)
>Hoenn Easily Route 119 (Weather Institute)
>Sinnoh Route 216 (First instance of the snow music)
>Unova Marine Tube but if only numbered ones count, I'll agree with Route 23
>KalosRoute 15/16 (For the Autumn leaves color palette)
>AlolaRoute 8 (Upper Akala w/Colress)
