=Changes from Diamond and Pearl=

Gameplay
Over local wireless, there is a new feature where the player and their friends can put their Pokémon Eggs in and randomly swap.
 * The Wi-Fi area has been enhanced with the new Wi-Fi Square, which supports up to 20 people at once. The new area seems to focus exclusively on mini-games, which include Rapid Wobbuffet, where players hit a Wobbuffet, and Merry Mime Jr., where players can balance Mime Jr. on a ball.
 * There is a new key item called the Battle Recorder (given to the player by Handsome when the player first meets him in Jubilife City), which allows players to record battles in the Battle Frontier and Wi-Fi, and share the records with other players over the GTS. Battle records can be rated by other players when viewed, and the most popular battle records are displayed for all to see. Players can also take snapshots of their PC boxes and share them with other players in a similar fashion.
 * The GTS has now incorporated an e-mail system that allows players to be notified of completed trades. Notification messages are sent to the player's actual e-mail address.
 * The Sinnoh starters are now allowed in a newly-expanded Amity Square, allowing a total of 20 Pokémon to enter the park.
 * HM05 (Defog) is now located on the bottom floor of the Solaceon Ruins, instead of Pastoria's Great Marsh.
 * HM04 (Strength) is now obtained from Riley on Iron Island, instead of in the Lost Tower.
 * On certain days of the week, there are Trainers that the player can challenge in certain Pokémon Centers, who are located in front of the Center's desk

Storyline

 * The player meets Professor Rowan and the opposite gender character earlier, and obtains their starter Pokémon on Route 201.
 * The very first battle is against the player's rival who, following tradition, has chosen the starter Pokémon with an advantage against the player's starter.
 * The player and the rival now encounter Cyrus at Lake Verity at the beginning of the game. The player will also meet Cyrus at different areas, such as the Eterna City statue.
 * A double battle with the player's rival against Flint and Volkner occurs at the entrance to the Battle Frontier.
 * Dawn/Lucas no longer gives the player the Dowsing Machine or the VS Seeker near the Route 206 junction. Instead, she/he now meets the player at the entrance to Mt. Coronet.
 * Some of Sinnoh's Gym Leaders have been reordered. Fantina is now the third Gym Leader, Maylene is the fourth and Crasher Wake is now the fifth.
 * Team Galactic's plans for world domination and the layouts of their HQs, such as their hideout in Eterna, have been changed. In addition, they openly recognize their goal, and are more villainous.
 * The player is now able to challenge all the Gym Leaders of Sinnoh to rematches, as well as the player's tag battle partners from throughout the game (Cheryl, Buck, Marley, Mira, and Riley) can also be challenged in a restaurant located in the Survival Area, known as the Trainer Café. Each opponent has a team of five Pokémon, with levels between 65 and 78.
 * The Elite Four's Pokémon are stronger after the player visits the Battle Zone, with levels between 65 and 78.
 * Team Galactic gains control of Stark Mountain under the command of Pluto; it is up to the player, with help from Buck, to defeat them.

 * The template in battle for a Pokémon's name, level, and HP is now a dark gray instead of white, and its shape has also been changed.
 * When entering new areas, the location labels in the top-left corner of the screen have been redesigned, similar to their update between Pokémon Ruby & Sapphire and Pokémon Emerald.

=Connectivity=


 * Pokémon Platinum can connect automatically to Pokémon Diamond and Pokémon Pearl once the player has access to a Pokémon Center. This game, however, is unable to connect with My Pokémon Ranch, but is able to connect to Pokémon Battle Revolution and to Generation III games. It is known that Nintendo plans to release a patch that will allow My Pokémon Ranch to be compatible. It is unknown if the patch will be for Japanese and other language versions of the software, or if those outside Japan will have to wait for their own versions of the patch
