>>25035878If you wanna play ORAS for the game, then play one of the popular difficulty hacks instead.
If you wanna play a Pokemon game to trade, battle, dick around, etc, then play XY. You don't miss out on much, just a few mega evolutions and then some in exchange for a better game.
Frankly, I bought neither, bought PSMD, played Rutile Ruby, and plan to buy Z or whatever it is later.
