>>19648101That last part is crucial to my idea: the Emerald key.
It would work like this:
Lets say I get AlphaSapphire. It has all the obvious extra features like Move tutors, the Battle frontier in it as expected. But the story stays true to RS (bar primal forms and new megas). Team Aqua does their thing, awakening Kyogre, who turns Primal and goes on rampage, I stop it, and beat the E4, credits roll.
This unlocks the Emerald key.
The Emerald key can only be used on a New game.
Meaning I can use it in 2 possible ways:
-Delete my Alpha Sapphire save file, use the key, and start a new game.
-get a second game, lets say Omega Ruby this time, bring the Emerald key over from my Alpha Sapphire, use it, and start my game.
in both cases, certain crucial parts of the game are now different. Some new entraces have shown up (like Magmas deep base in Mt.Chimney), events have changed or been added, crucial trainers teams adjusted.... essentially, I am now playing my game as if I had bought an Emerald remake instead of Omega Ruby.
The plot involves both teams in the proper places they belong, the climax is the legendary fight, Rayquaza is needed, in its own primal form no less.
