Not to mention that the rest of Sinnoh has multiple locations open up like Rotom appearing in the Old Chateau, Cresselia roaming after you go to Fullmoon Island, Snowpoint Temple being open with Regigigas at the bottom, Sendoff Spring which takes you to Turnback Cave where Giratina resides, Pal Park opens up if you want to transfer Pokémon from your GBA games, the second half of Victory Road becomes accessible and it leads you to Route 224, the point of which is to lead to Shaymin at the Flower Paradise and Seabreak Path, while Darkrai can be found at Newmoon Island, and Arceus is at the Spear of Pillar after it becomes the Hall of Origin. And the Poké Radar, dual-slot mode, swarms, Super Rod, updated Underground/Trophy Garden/Great Marsh lets you almost TRIPLE the size of your Sinnoh Dex.
