>>56141624For me it's the care that was put into each location.
People like to shit on Castelia for its music, but I still think to this day it's the most realized representation of a big city that we ever got in a core game.
The cities and towns in general were great honestly. Virbank, Driftveil and Undella are still some of my favorites to this day.
Hell you have stuff like Anville town which they didn't really need to put in but they still went and did it and I didn't even discover it during my first playthrough.
Then there's other stuff like the bell in the Celestial Tower or the beating all of team plasma to reach the top of Dragonspiral Tower only to find you're too late.
The Victory Road is probably the best in the series, and what transpired at the League and the climax of BW's campaign was a very unique twist on the usual formula.
The seasons should've lasted a week instead of a month, but it was still a nice finishing touch to make the world of pokemon feel more alive than ever.
The memory of reaching a rainy Virbank at night for the first time is something that will stay with me for the rest of my life.
