I really didn't like ORAS and the fact that it ignored many of the storyline and content additions from Emerald.
On Storyline: Why would they hybridize
Ruby and
Sapphire's plot again? That made sense for
Emerald, not ORAS. And this isn't a simple thing like the Suicune plot in
Crystal and HGSS since it barely affects anything and they simply moved Suicune to the post game in Kanto instead of replacing Ho-Oh's placement in
Gold's plot.
Content: The only major content
Emerald had was the Battle Frontier (which should have been added). The rest were mechanical or simple changes or something to accommodate the fact that
Emerald was a single game where
Ruby and
Sapphire weren't (Latis, etc.). And many of the mechanical and simple changes were still in there (NPC Multi Battles, all of the major and minor changes to make various abilities and items more useful, like Magma Armor and Synchronize*). I mean, it even kept the Johto starters and added the Sinnoh and Unova starters as well!
To be angry at the lack of a Frontier is fine, but to act like
Omega Ruby and
Alpha Sapphire should be identical to
Emerald is mind boggling.
*Well, some where further improved in later generations.
