Some Personal Desires/Expectations for Omega Ruby/Alpha Sapphire
-More frequent double battles. Emerald was great at increasing the amount of double battles in Hoenn, and i'd expect to see the same amount of double battles in the remakes of the games that introduced the battle mode.
-R/S Leaders and E4 (Please!) I disliked in Emerald how the last gym leader and the champion used the same type of pokemon. Plus, i'm a little biased and i like Steven as a Champion.
-R/S Storyline. Liked the personal confrontation with Kyogre/Groudon in Sootopolis for each version, though Emerald's confrontation between the two mascots with Rayquaza intervening was great as well.
-elimination of the altering cave. Whereas in R/S/E it was used to find different pokemon via mystery gift, i think the location of where it is now could be re-purposed as the lair of Regigigas. Expounding on this, i think Regigas should be an added in-game event legendary given the three Regis were introduced in Hoenn.
-New Battle Frontier facilities. Though a lot of the Battle Factory facilities were great, i think there should be different facilities to mark the changes that the game has undergone overtime. But that's just me.
-Mega evolutions for Sceptile, Swampert, Groudon, Kyogre, Eon Duo.
-Named Team Executives (i.e. Shelly, Tabitha) will be present like in HGSS and have their own character models.
