And two of those facilities were not post game.
I don't think Black & White were known so much for there post game and more for all the things they just got right.
It's nice to have character cameos, but it's even nicer to get to fight them.
And not just a handful of characters once every 10 battles. You could fight all of a region's gym leaders or all the Pokemon League champions in a single bracket. That was honestly something that could not be topped.
The Black Tower/White Treehollow was a very different facility from your usual Battle Tower, and it gave us a cool new unique character, Benga, who was Alder's grandson. He really gave off Gary vibes and I personally liked him.
Those two facilities aren't really comparable to the the Battle Tower/Subway/Tree, and they're a lot more fun and fair than almost anything int he Battle Frontier.
