If you liked the earlier pokemon games for GBC. For example Yellow ,red, and blue versions. This is it, with much improved graphics, sound, gameplay, and additional areas, including more pokemon to catch. The graphics in this game are great, finely detailed pokemon and land. When you enter a cave, forest, or any other place, a picture appears with the actual graphics for that place. Now the pokemon picture in your party looks more defined and has the actual picture of that pokemon, insted of having a single icon or picture for a group of pokemon. So, overall the graphics are prettygood. The sound hasn't improved much, but new background music is pretty nice. I stiil wish that they made a clear voice for each pokemon, so that when a battle begins you could actually hear the cry of the pokemon, not fake and weak cries. New Islands are there to be explored, including some of the new pokemon from the other series,:larvitar, Unknown, and many more. So, this game will keep you from which pokemon to keep as your party.This makes the game much longer. Anyways after you beat the game, you can still continue to train your pokemon or beat the elite again, I mean you can do anything after you beat the game.You can trade from colosseum if you have the Gamecube to GBA connection.Which is great to increse your pokedex. The new Wireless Adapter that comes with it is pretty handy, if you have other people around that have Fire Red or Leaf Green. You can trade from other players wirelessly. You can chat with other players around you.Of course you can also battle them. So, it is great since it's free with the game. Afetr you beat the game you'll never get tired of it as you play it to try to train other pokemon to add pokemon to your pokedex. This game is very valuable. Make sure you get this game to add it to your GBA game collection. This game is a gotta have game.
