Almost everything new that was added to this game from the originals was great. Flying above the region, the new megas, Zinnea and the Delta episode, the new original music, all amazing.
However, a lot of the things they changed fell extremely flat for me. The Gen 3 music in the Gen 6 soundscape did not transfer well in a lot of the music (less brass, bad rhythm, etc), how easy the game was (Pokemon is for kids but as a kid I'd feel my intelligence insulted), and of course no Battle Frontier.
Some really good things in ORAS but it fails in being a good remake, especially when they nailed it with HGSS.
