>>28110636ORAS has most of the good features of XY except customization along with some new additions of its own.
The main game itself is actually pretty fun, its just that its difficulty level is pretty low, you get handed some very powerful tools (Exp Share All, Latios or Latias and your megastones) pretty early on, and its post game is underwhelming.
On the plus side, its got secret bases, great Pokenav features including Dexnav, contests with a new cutie 3.14 character, revamped and improved (characterwise, they're still pushovers) Team Magma and Team Aqua, and the rematch E4 and champ is actually pretty strong as these things go.
Its a good platform for challenge runs.
The best one being the Good Son playthrough where you run mononormal to make Norman proud.
