Pokemon Yellow, I think, is really a big waist of time if you have already bought Blue or Red versions. All that is different is that it shows up in a tad more color and a little Pikachu follows you around. Stick with the Gold or Silver version once it comes out. But if you don't have blue or red and can't wait, buy this one, it is no more expensive and you get cute little Pikachu following you around. Just don't trade that Pikachu otherwise it won't follow you around anymore, even if you catch a new one!!!
