>>28312833ORAS is mostly nostalgia pandering; not worth playing if you aren't attatched to the originals, haven't played the originals, or are just playing to have a current gen game that isn't shit.
It's way easier than the originals, and lacks some features the old game had (pokeblock making, good contests/that rental pokemon tent, the cool pokenav with the calling feature), but has some new cool features (dexnav, online secret base sharing, delta episode, soaring).
I wouldn't recommend playing it after having played emerald, as most changes will bother you, unless you're fueled by pure nostalgia.
