Lati@s, S.S. Tidal, Battle Tower, Sky Pillar and a Trick House challenge. That's not counting side stuff like contests.Did RS have a lot of post game content? If I remember correctly, there was a shitload more to do than in XY.
Emerald added a lot more, like the Battle Frontier, Desert Underpass, Safari Zone expansion, Steven battle, Gym leader rematches, Groudon/Kyogre etc.
