Pokemon Emerald is the third in the series from the jewel versions(Sapphire, Ruby) it is a bit more advanced than Sapphire and Ruby but still the same adventure also a man called Scott will now and again pop up and once you complete the pokemon league he will show you to a place called battle frontier, this is a place for powerful trainers. Other things are different too like the colour of the characters backpack and headband are green instead of black and yellow. The game will seem fantastic for pokemon fans who do not have pokemon Sapphire and Ruby but for those who do have it, it will not be much of a supprise .
