Just when I was getting burned out with the GB games this one was amazing and unique! I love the slightly more focus on the story, maybe even a bit more then any of the NES games so far. They also brought back the letter collectables I liked from 5. While not completely necessary the store was a really good addition along with the new tank items. It's just a cosmetic differences but I also liked the stage select menu here too, instead of being the normal grid they tried to do something new.
