remake pokemon gold and silver

Pokйmon Red and Pokйmon Blue are the first two installments of the Pokйmon series of role-playing video games, first released for the Game Boy in Japan in 1996, later released to the rest of the world in 1998 (North America) and 1999 (Europe and Australia). Set in the fantasy world of Kanto, the game's stories follow the progress of the central character in his quest to master Pokйmon battling. Both games are independent of each other but feature largely the same plot and, while both can be played separately, it is necessary for the player to trade among the two in order to fully complete the game.

Fire Red and Leaf Green feature the original 151 Pokйmon from the original Game Boy games, along with many others from later games in the series. While players can still play the originals, they can not trade Pokйmon to the Advanced generation. The upgraded games bring the Kanto region Pokйmon, and experience to the third generation of Pokйmon (the Advanced generation). These games finally complete the loop; allowing players to catch all 386 Pokйmon that existed at the time, since many of the Kanto (and Johto) Pokйmon are unavailable in Ruby, Sapphire, and Emerald. The games were very well received, with the improvement of the graphics, and the inclusions of extras, with 10.66 million sold.


Pokйmon Gold and Silver introduces a separate region from the one in the original Pokйmon titles (Kanto). This new region, named Johto, offers one hundred new Pokйmon for players to capture and discover with a new version of the Pokйdex; other new features include the Pokйgear, Berries, a full-color world, special Pokйballs, and breeding Pokйmon to produce Pokйmon Eggs from which baby Pokйmon hatch.

Additions
More specialized Pokй Balls were introduced in this game. A Lure Ball is more effective if used against a Pokйmon caught with a fishing rod, and a Friend Ball will make a Pokйmon more comfortable and friendly to its trainer much more quickly. To obtain these balls, Apricorns must be picked from special plants found throughout Johto, and Kurt in Azalea Town will fashion these into the different balls based on their color. However, Kurt can only make one ball at a time, and players must wait until the next day for Kurt to finish the ball. Although these specialized Pokй Balls and Apricorns were not in future generations, there were other specialized balls.
The game introduces shiny Pokйmon, i.e. Pokйmon which have a different coloring than normal Pokйmon of their species, and which appear very rarely (estimated to be a 1/8192 chance). In this second generation of games (though not the third generation which followed on GBA), these Pokйmon often have better stats than regular non-shiny Pokйmon, but can never get the maximum stats for that species. There is one exception to the shiny Pokйmon system: A Red Gyarados can be found at the Lake of Rage. Since it is part of the storyline, it is impossible not to encounter this Pokйmon.
Pokйrus (Pokйmon virus) was introduced. The virus is even rarer (about a 1 in 32768 chance) to get than a shiny Pokйmon, and doubles the Special Experience (a concept adapted to later installments of the Pokйmon series as effort values) that the players Pokйmon gain each time the infected Pokйmon participates in battle (provided the battle is won and the infected Pokйmon does not faint).
Six legendary Pokйmon were introduced:
Raikou, Entei, and Suicune are three mammal-like Pokйmon that have been informally called "Legendary Dogs," "Legendary Cats," and "Legendary Beasts." (This is a point of hot contention among fans, though Nintendo usually refers the them by their individual names or as Legendary Pokйmon, only once having called them cats.) They wander around Johto after they have been awakened at the Burnt Tower, changing locations every time the player moves to a new location, though they can be tracked with the Pokйdex once sighted. If encountered, they instantly attempt to run away, and if unable, use the move Roar, which ends the battle by forcing the player's retreat. Because of this, many players catch them with a Master Ball to avoid the hassle of attempting a battle. However, if the player does engage them in battle, any HP loss or status effects will stay the next time they are encountered.
Ho-Oh and Lugia are two new legendary birds; Ho-Oh is depicted on the cartridge of Gold while Lugia appears on Silver. Of the two, the one depicted on the game cartridge is encountered at level 40, while the other can be found at level 70 after the player defeats the Elite Four. Ho-Oh is said to control Raikou, Entei, and Suicune while Lugia is said to control Articuno, Zapdos, and Moltres from Pokйmon Red and Blue.
Another legendary Pokйmon, Celebi, is analogous to Mew in the original set of games. Celebi can only be obtained through devices like GameSharks or through official Nintendo promotions, though it was available through a mobile phone connection in the Japanese Crystal version.
Several new moves were also added; to allow Pokйmon to be traded back to the first generation games, a move deleter was introduced. He can be found at Blackthorn City. The move deleter can remove any move, including HM moves, which previously could not be unlearned once taught to a Pokйmon other than through the daycare which has the rights to replace the Hms

Time
In addition of other new features, a time system was also introduced. At the beginning of the game, Professor Oak is awakened by the player before the traditional intro sequence. He asks the player the time. The games clock is set accordingly. Afterwards, the protagonists mother will ask about the day of the week and Daylight saving time.
Throughout the game, Pokйmon appearances are influenced by time of day: morning, day, and night. Hoothoot, for example, only appears at night (since its an owl-like Pokйmon). Certain events are also determined by the day of the week, like the bug catching contest which is held in Goldenrod City's national park on Tuesday, Thursday and Saturday. Depending on the day of the week, either "Pokйmon March" or "Pokйmon Lullaby" can be heard on the Pokйgear radio. Pokйmon March raises the chance of a Pokйmon appearing when the player walks into the grass, while Pokйmon Lullaby decreases that chance.
In addition, Eevee's two new evolutions, Espeon and Umbreon, will only appear at a certain time of day once Eevee levels up after becoming extremely attached to its trainer. Eevee will only evolve into Espeon in the morning or daytime and into Umbreon only at night.

Type changes
Two new types were introduced, Steel-type and Dark-type. These two types serve to balance the Psychic type, whose only weakness consisted of Bug-type moves; however, Bug-types lacked any powerful offensive moves in past games. In the second generation games, moves like the powerful Megahorn (120 power move with 85\% accuracy) were added. In addition, the Steel and Dark types also balanced the Fighting type, which was only "super effective" against Normal, Ice and Rock types ( all of which are rarely used in competitive battling) ; Steel and Dark are both weak against Fighting. Steel-type Pokйmon are known for their very high defense; they are highly resistant to many types and their moves are strong against Ice- and Rock-type Pokйmon. Dark-types are immune to Psychic-type moves and have moves with malicious-sounding names, like Bite and Thief, which are super-effective against Psychic-type. Dark-types are also strong against Ghost-types, thus being the only type that has an attack advantage over Ghost-type Pokйmon besides Ghost-type moves themselves. The Dark-type Pokйmon are also weak against Bug-type attacks.
Another major change from the original series was the splitting of the Special stat into Special Attack and Special Defense. Again, this increased aspects of strategy, for Pokйmon were now more specialized. Some were good special attackers, while others were better physical attackers; the same now held true for defense and special defense. For example, Cloyster has a decent Special stat in Red/Blue/Green/Yellow, but in all later games, has a decent Special Attack, but low Special Defense.
Some type match-ups were changed as well. In Pokйmon Red and Blue Ghost-type moves had no effect on Psychic-types; this was changed to super-effective as it was in the Pokйmon television series. Poison-types originally were effective against Bug-types and Bug-types ineffective against Poison; this was changed to Poison doing normal damage to Bug and Bug becoming not very effective against Poison, seriously limiting the effectiveness and usage of Bug-types and Poison-types. Ice-type moves were also made not very effective against Fire-types (previously they did normal damage). In this version several moves had their type changed. For example, the move Gust was a Normal-type in the first generation games but is now a Flying-type move; the move Bite was a Normal-type move in the first generation, but now is Dark-type. Two Pokйmon, Magnemite and Magneton are now Electric/Steel (in Red and Blue, they were pure electric).

Holding items
A new feature, Pokйmon being able to hold items, raised the bar for strategy, because players could use held items to outspeed their rivals (Quick Claw), heal ailments (berries), restore HP in battle (Leftovers), boost element-specific attacks (Miracle Seed), or increase the Pokйmon's happiness (Soothe Bell), among other uses.
Held items can be acquired on their own, but some are found already attached to Pokйmon. For example, trading a Kadabra/Alakazam may result in obtaining a Twistedspoon, which is the only way to obtain this item. If the Pikachu that is given by Oak at the beginning of Pokйmon Yellow is traded to Gold or Silver, it will be holding an item called the Light Ball, which doubles Pikachu's Special Attack power. Because of this, many players do not evolve their Pikachu and instead keep the massive power boost. Many other wild Pokйmon hold items too, such as Leftovers from Snorlax and Lucky Egg from Chansey.

Gold and Silver originals made it to the top two spots on the charts for weeks after release and the remakes for Pokemon red and blue were very successful. I think making remakes for gold and silver on GBA or Nintendo DS would make the Pokemon companies even more money.
