"Pokemon Silver" and "Gold"
"Pokemon Silver" and "Gold" introduced an additional 100 Pokemon, bringing the total count of Pokemon up to 251. The games took place in a new region, Johto, and provided two new Pokemon types: Steel-type and Dark-type. A new plot was introduced, again involving Team Rocket, and the goal was the same as the previous games; defeat all eight gym leaders and the Elite Four to become the Pokemon champion. However, all of the gym leaders and Elite Four had changed from "Red" and "Blue." The inclusion of time provided a new element to the series, as certain Pokemon could only be captured during certain parts of the day.
Enhancements from "Pokemon Red" and "Blue"
"Pokemon Silver" and "Gold" featured a number of enhancements over "Pokemon Red" and "Blue." The most visible enhancement is the graphics; Pokemon sprites are better detailed and the color palette is improved over the black, white and grey color scheme of the original games. "Gold" and "Silver" were the first "Pokemon" games to feature specialized Pokeballs designed to capture certain types of Pokemon easier, such as the Lure Ball, more effective against Pokemon reeled in with a fishing rod. The bag has been divided into multiple sections, making it easier to find items, and the game is twice as long, as players are able to explore the region of Kanto after finishing Johto.
Differences between "Gold" and "Silver"
"Pokemon Gold" and "Silver" only feature a few differences between each other, most noticeably in the types of Pokemon available. "Pokemon Gold" features Sandshrew, Sandslash, Mankey, Primeape, Growlithe, Arcanine, Spinarak, Ariados, Gligar, Teddiursa, Ursaring and Mantine as its exclusive Pokemon. "Pokemon Silver" includes Ekans, Arbok, Vulpix, Ninetales, Ledyba, Ledian, Meowth, Persian, Delibird, Phanpy, Donphan and Skarmory as its exclusive Pokemon. In addition, both "Gold" and "Silver" had different sprites for a majority of its Pokemon, resulting in graphical changes when battling. The plot, gym leaders and map are identical across both games.
Compatibility
"Pokemon Gold" and "Silver" were released for the Game Boy Color and were not compatible with the original Game Boy, due to the enhanced color palette and newer technology found within the Game Boy Color. The Game Boy Advance, released in 2001, also has the ability to play Game Boy Color cartridges including "Pokemon Gold" and "Silver." The Game Boy Advance SP, released in 2003 as an upgraded version of the Game Boy Advance, is the last system that features compatibility with the Game Boy Color. Commonly known as the SP, it allows players to play "Pokemon Gold" and "Silver" in the same manner as the Game Boy Advance.
