In a trailer posted today, Nintendo tells us there’s still more to do in the Hoenn region. Even if you’ve beaten all the gyms, the Elite Four and started on the post-game action, there’s still a lot left. Watch the trailer below to see there’s still a bit more information for you to complete the game.
There’s a bit of info about encountering legendary Pokémon, where to find some Mega Stones and tips on secret bases. They also mention you’ll be able to obtain starter Pokémon from other regions, but don’t say how. I guess that’s up to us to figure out.
