I love pokemon and I could not wait for this game, and it was pretty awesome to play. It has a great balance of new and old pokemon, great cell shading, and lots to do. I'd love to go into everything, but I think it's best to find out how awesome it is for yourself. Just get it, especially if you're a pokemon fan, you'll be glad you did.
There have been plenty of pokemon games since red and blue' even yellow. Pokemon x and y bring refreshing 3d graphics to an old formula. The right mechanics have been tweaked, ie experience share, and the the old stuff that makes the game so good are the same. This game also brings in new creatures while also honoring the original.
