All of us old Pokemon players will remember Pokemon Gold and Silver from years ago, released on the GBC. The memories I had on there were lost when my Gold's battery ran dry.
Now we can play Gold and Silver again, improved to the new standard. Updated with better graphics, the new pokemon and moves, and compatibility with Diamond/Pearl/Platinum. There are also a lot of new changes that really make HeartGold and SoulSilver shine.
Now the first Pokemon in your party follows you, it's pointless, yes, but is quite cute. There is a new wireless device called the Pokewalker, which is a pedometer which gives your Pokemon experience points while you walk.
You can get the original legendaries in the game, meaning Ho-oh, Lugia, Raikou, Entei and Suicune. There are also a lot of new additions, you can get Kyogre or Groudon in HeartGold or SoulSilver respectively and if you trade both of them onto one game you can get a Rayquaza!
You can get a Lv1 Dialga, Palkia or Giratina with a special event Arceus. The legendary birds and Mewtwo from Kanto are also in the game. The last mentions are Latias and Latios, who can be found roaming about, like the legendary dogs.
The PokeGear is back, and so is the phone system. Now you can rematch trainers you've battled before if they call you. The Battle Frontier from Platinum is in this game, copied almost exactly from Platinum.
This is a great game, for those who have played Gold or Silver or for those who haven't. HeartGold and SoulSilver are amazing additions to the Pokemon series. When you can't think of anything wrong with the games, you start to wonder how Nintendo would ever top these games.
