I would be fine if they just added a bunch of Pokemon to the existing region. Might be cool to go after Norman with a Croagunk!
Other cool options would be to expand the routes a bit, add some kind of landmass below the water routes, add some misc islands to the water routes, or hell; add another region to visit! But my goodness, secret bases better return in the remake if a remake happens.
This be good. Add more large Islands to explore(connecting them with bridges). Add more pokemin per route. Add more offshoot areas to the game. And perhapps make the the hoenn dex split unto two 200 pokemin dexes. One could be like the main land dex the other could be the island dex. --- .....said an almost 30 year old married guy driving a van part time for a living 3ds my fc, 0602-6823-9646, my wifes 0146.9112.0071
Since PokeCenters and Marts are in the same building now, they can replace the mart building with something else. It could be the same thing in every town, or not. --- 1 universe, 8 planets, 204 countries, 804 islands, 7 seas, 7 billion people and it is JUST you. - PhaseSlaethe
The dex would be split; LAND/OCEAN dex. i could see a third area rise up from the ocean (mountain rises up from the ocean high into the sky in late game, or maybe it's already occurred? maybe even a town and gym up there? This area would obviously house Rayquaza) where you and other trainers travel to (SKY dex), and lots of sky battles added. There'd also be plenty of dive battles in the water.
I could also see a post-game area "Isle of Myths" "Legendary Isle" or something, where there's a big amount of legendaries to catch that you can't in X/Y. It's basically the post-game extra story, about this mysterious place that legendaries flock to, that maybe GF will give hints to future legendaries,like maybe some uber legendary created this as a haven for the other legendaries or something.
