1. Day – Night Mechanism
The Day – Night mechanism may be something quite popular and familiar in RPG games at the present time, but in an era 20 years ago and on a handheld gaming system, it was very respectable.
While this isn’t the only new element GameFreak did on the Game Boy Color, it’s one of the most notable.
2. Added 100 new Pokémon
Although there are not too many new Pokémon added like in other games, the number 100 seems to be quite suitable for Crystal.
In addition, Crystal also produced countless interesting Pokémon, and are still loved by Pokémon fans to this day, such as Heracross, Umbreon or even Tyranitar.
3. The appearance of Pokémon Shiny
Hunting for Shiny Pokémon seems to be a hobby for fans these days.
One thing worth remembering here is that the `glowing` Pokémon first appeared in the Crystal version.
4. Fundamental mechanisms and features for the entire game series
Crystal and the 2nd generation versions not only `upgrade` the features in the first version but also contribute to building features that are the foundation of the entire Pokémon game series and later games.
These features include: Shiny Pokémon, special Pokeballs, creative evolution system, rematch with opponents, legendary Pokémon moving around the map, friendship system – happiness for Pokémon
5. The game expands after completion
If in Pokémon Red & Blue, you just have to beat the Elite Four and become the new champion to finish the game, then in the next version, everything becomes much more interesting.
Accordingly, after completing the game for the first time, players can return to the Kanto mainland and win 8 badges on this continent.
