The second generation of Pokémon games, also known as the “Gen II” games, was released in 1999 and includes Pokémon Gold, Silver, and Crystal. This generation introduced 100 new species of Pokémon, bringing the total number of species to 251.
The second generation games take place in a new region called Johto and feature new cities, towns, and routes to explore, as well as new Gym Leaders to battle and new Pokémon to catch. The games also introduced several new gameplay mechanics, including day and night cycles, breeding, and held items.
One of the most significant additions of the second generation is the concept of Pokémon eggs, which can be obtained by breeding two Pokémon and then hatching the egg to reveal a new Pokémon species. This generation also introduced a new form of evolution called “shiny Pokémon,” which are rare alternate colorations of certain species that have a different appearance than their standard forms.
Overall, the second generation of Pokémon games expanded upon the success of the first generation and added new dimensions to the Pokémon world, further solidifying the franchise’s popularity and longevity.
