I actually played the game till I was 13, I have Red, Silver and Sapphire(which was actually a waste of money, I've played it for only 5 hours). I have to admit, their is nothing wrong with the games, accept, you can't expect me to buy 15 different pokemon games, I mean: Red, blue, yellow, silver, gold, crystal, ruby, sapphire, Emerald, Pinball, the card game, Pokemon stadium 1 and 2, Pokemon snap, Pokemon Colloseum were you have to collect 350 of those things.
I've also watched some of the episodes, cause I was curious, but they are all the same. They're all like : OMG Team Rocket has taken Pickachu (again!), man those are the worst series I've ever seen. I also never bought any of those trading cards, cause I think they are really a waste of money.
My opinion is: Pokemon was pretty funny 5 years ago, but it's getting really old now and they should come up with something new.
