Generation IV introduced 107 new Pokémon across Sinnoh and made one of the most impactful mechanical changes in the series: the Physical/Special split. Before Gen 4, whether a move was physical or special was determined by type, not the move itself. This change fundamentally rebalanced the competitive metagame. Pokémon Platinum (2008) is the definitive Gen 4 experience, featuring the Distortion World, expanded storyline, and the Battle Frontier.

Challenge Run Tip
Pokémon Platinum is the top Gen 4 pick for challenge runs. It has better pacing than Diamond and Pearl, a more complete Pokédex, and the Distortion World adds a memorable mid-game challenge. Brilliant Diamond and Shining Pearl are faithful remakes but lack the Battle Frontier, making Platinum the preferred choice for experienced players.
Frequently Asked Questions
How many Pokémon are in Generation 4?
Generation 4 (Sinnoh) introduced 107 new Pokémon, from Turtwig (#387) to Arceus (#493). Notable additions include Lucario, Garchomp, Togekiss, and Glaceon — all of which remain competitively relevant.
What is the Physical/Special split introduced in Gen 4?
Before Gen 4, every move of a given type was either always physical or always special — Fire moves were always special, Normal moves were always physical. Gen 4 changed this so each individual move is classified as physical or special regardless of type. This allowed Pokémon like Gyarados (high Attack, Water-type) to finally use physical Water moves effectively.
Is Pokémon Platinum better than Diamond and Pearl?
Yes, for most purposes. Platinum includes all the content of Diamond and Pearl, adds the Distortion World dungeon, expands the Pokédex available in-game, has better pacing, and includes the Battle Frontier post-game. Brilliant Diamond and Shining Pearl (2021) are faithful remakes of the originals but do not include the Battle Frontier.
