I'm very surprised with some comments and I'm becoming more and more convinced, that ORAS is seriously underrated, and most likely will continue being underrated until time passes and people judge it with better perspective. (It happened to me with B/W).
However, I must say that I'm really surprised with some fans' personal bias...
For example, HGSS adds a storyline from Crystal about Eusine and Suicune and it is considered a brilliant decission.
But then ORAS adds a BRAND NEW, original and exclusive storyline about the brand new Mega Rayquaza, and Deoxys, and you even visit SPACE... and some people are criticizing it and wanting back Emerald's MUCH more predictable (and already seen) storyline!
