Advances in gameplay
Much like how Generation II enhanced Generation I mostly by building on its features, Generation IV builds on the features introduced in Generation III. The advancements introduced in Generation IV include:
- The addition of 107 new Pokémon, bringing the total to 493. New evolutions and pre-evolutions abound in this generation, including ones for long-time favorites such as Electabuzz and Eevee.
- The addition of 113 new moves, bringing the total to 467.
- The addition of 47 new abilities (and removal of the unused Cacophony), bringing the total to 123. Many older Pokémon can now have one of two abilities, rather than the single ability they could have in Generation III.
- Four more boxes in the Pokémon storage system, bringing the total to 18, for a total of 540 Pokémon.
- Another new region to explore, Sinnoh, yet again with its own Gym Leaders and Elite Four. Player characters are again changed.
- Four new variants of Poké Ball, retaining the seven introduced in Generation III.
- A new villainous team, Team Galactic, whose intent is to capture Dialga and Palkia, said to be the creators of the Pokémon universe, and remake it in the image of their leader, Cyrus.
- The return of the time system from Generation II, with enhanced transitions between the time periods of the day.
- A three-dimensional rendering of the overworld, rather than just sprites, with the same style seen in previous games.
- Moves are now designated physical or special based on the move itself, rather than its type.
- Pokémon are now able to be traded and battled over the internet through the Nintendo Wi-Fi Connection.
Alterations from Generation III include:
Further additions in Platinum include:
- Another new Battle Frontier, with several different facilities than the one in Hoenn.
- Ability to record and share battles with other players and in the Battle Frontier over the Nintendo Wi-Fi Connection.
- Sinnoh Pokédex is expanded, making the total of 210 Pokémon in the Sinnoh Pokédex.
Further additions in HeartGold and SoulSilver include:
- Main article: Sinnoh
Like Generation III, Generation IV introduces a new region disconnected from all previous ones, the Sinnoh region, found far north of Kanto. Being that it is so far north, snow can be found on its northern tip, as well as in the mountainous center of the region. Much of the western half of the region is rural, while its east is comparatively urban, in a similarity to the continental area shared by Johto and Kanto, respectively.
Though it was initially rumored that the Grass/Fire/Water setup that had been the norm for the past three generations would be replaced with a Dark/Psychic/Fighting trio, these rumors were later proven false. At the beginning of the journey, players must choose from the Grass-type Turtwig, the Fire-type Chimchar, and the Water-type Piplup to defend themselves from a wild Starly in Diamond and Pearl, or be given one of the three by Professor Rowan directly in Platinum.
Like the other three regions, Sinnoh has its own set of eight Gym Leaders. This set specializes in the same types as Gym Leaders from other regions, though not in the same order. Like always, badges and TMs are given away by defeated Gym Leaders.
- Main article: Johto
Much like Kanto was featured a second time in Generation III, Pokémon HeartGold and SoulSilver cause Johto to be featured a second time in Generation IV.
Much as Kanto's Generation III starters were the same as in Generation I, Johto's starters have not changed. Professor Elm offers Chikorita, Cyndaquil, or Totodile to the player as protection on an errand to Mr. Pokémon's house on Route 30.
As would be expected, Johto's Gym Leaders are the same as before, but many give out different TMs than they gave out in Generation II.
- Main article: Kanto
In its fourth appearance, Kanto returns in HeartGold and SoulSilver much in the same way as it did in Generation II (as a post-League area).
Kanto's Gym Leaders are the same as in the original Gold and Silver, changing slightly from the group who were there in Generation I and Generation III. All Kanto Gym Leaders give TMs, unlike in Generation II.
Other Generation IV games
Pokémon Battle Revolution features a Pokémon Stadium-like arena for battle, allowing Diamond, Pearl, Platinum, HeartGold, and SoulSilver to link to it through wireless communications between the Nintendo DS and Wii, much like previous generations' games would link to Colosseum, XD, Stadium, and Stadium 2. Battle Revolution also features online battles with players around the world via the Nintendo Wi-Fi Connection.
My Pokémon Ranch lets players of Pokémon Diamond and Pearl deposit their Pokémon, via wireless communication, to a ranch owned by Hayley, who will also bring Pokémon to the ranch. Players can interact with up to 1,000 of their deposited Pokémon. An update for this game enables support for Platinum, as well as allowing storage for 500 more Pokémon, however, it has not yet been released to players outside Japan. It is unknown if another update will be released for HeartGold and SoulSilver.
- Every player character in all Generation IV games has a Wii in his/her room, referencing its status as the current Nintendo console during the generation. This is in contrast with Generation III, in which only player characters in Hoenn had a Nintendo GameCube, while player characters in Kanto had an NES.
- Generation IV's framerate is downgraded from Generation III: whereas Generation III games ran at 60 frames per second, Generation IV games run at only 30, like Generation I and II do. This is likely to prevent slowdown due to the 3D graphics.
- Due to the Generation II remakes, and the inclusion of Kanto in them, Generation IV has the largest number of accessible regions (in the handheld games) of all; Generation I had only one (Kanto), Generation II had two (Kanto and Johto), Generation III had two (Kanto and Hoenn), whereas Generation IV has three (Kanto, Johto, and Sinnoh).
- Because Hoenn was not included in Generation IV, its Gym Leaders, Elite Four, and Frontier Brains lack the now standard animated battle sprites and close-up headshots. Lorelei and Agatha, the only important Trainers from another region who are not in Generation IV, also miss out.
- The Japanese font, including its rendering, that is used in the dialogues of the international versions is different from the Japanese versions. This doesn't happen in Generation III, where international versions use the same Japanese font and rendering.
