Gotta catch 'em all! Still the greatest concept of a game no matter how many times it's been used.
Graphics: while sticking to the old top down view of the world, this new installment takes in some 3D liberties. Parts of it, mainly with trees, looking somewhat Animal Crossing-esque. The colors are bright, and the world is fresh. This is a pretty game.
Sound: Before I go on, let me say I was happy to hear the classic poke-center healing tones (da, da, da-dee-DA!). I did smile and it was good. The music is classic, still feels like the world of Pokemon and tends to keep you happy. The Pokemon's sounds are nothing new, simple growls and whatnot, but they do their part.
I love this game, I was a fan of the classics and I'm a fan of this. They added some great multiplayer aspects. They have an interesting underground bit where you can get some interesting items for your "secret base". Not needed, but fun nonetheless. If you're a fan of this series, or have never played but want a good RPG, get this. You will be glad you did.
