i usually get the one my little brother doesnt get. like he had red an i had yellow (well it doesnt really work there lol), he had gold an i had silver, he had ruby an i had sapphire, he had fire red an i had leaf green, so i guess u get the trend here lol. i usually buy the one that comes second when they name them cause everybody else gets the other one so alot more people should have the pokemon i cant get, an this will be especially important this time around with online trading.
