From there, maybe Mystery Dungeon RB or Colosseum.
In regards to the Mainline games - most have pieces that give a feeling, but they're generally restricted to small portions (Pokemon Tower, the Snow Routes in Sinnoh, etc.). Alola maybe has the most consistant atmosphere, so I'd probably give it to them if we have to choose one of the mainlines.
