Kanto is back and better than before
Leaf Green remains very similar to Red and Blue in terms of the role-play [a young kid from Pallet Town with a dream of becoming a Pokemon master] but that by no means is wrong, all the games have followed roughly the same storyline and yet it still remains a highly successful franchise, LeafGreen is a refined version with minor alterations which seem to make all the difference, the sprites have been improved and the pokeball actually looks like a pokeball and not the kind of ball you expected to see on a Pool table. The one on one battles remain enjoyable and overall generates a stronger experience to the gameplay.
Those who couldn't get enough of the Red and Blue versions on the GBC will simply not be able to resist the temptations that the new and improved Leaf Green has to offer.
