Pokemon ruby is a role playing game where you live in a world with some strange creatures that are called pokemon!
What you have to do is to find them and catch them all. To catch them you will need some pokeballs, but you will figure these things out for yourself. As you progress through the game you will have to fight in gyms to get eight badges. In every gym there is a gym leader that you have to battle with and win to get the badge.
What I personally like about this game, is that you can build your own team of pokemon and make them fight for you and I also like that almost every pokemon can evolve, learn new moves and become stronger.
But keep an eye for the legendaries. Legendaries are special pokemon that are really powerful, but really rare and hard to catch.
I really think is an amazing game and everyone should play it. So go ahead and catch them all!
