The games added many new things, such as a new computer storing system. There were also 100 new Pokémon added. The battle system was changed a lot, and added double battles. Abilities and natures were added to make the game more interesting and affect the way Pokémon grow and develop. Pokémon Contests were a new feature, where you perform moves for a judge, and are rating on their "condition", like a beauty pageant. Sweets called Pokéblocks were added to treat Pokémon.
