I just bought the game (BB had a sale, and GGC), and it is amazing. Even though it is short (Im at about 3:20 and near the end), it is AMAZING. Its what Games are all about. And for replay value, when you beat it, you unlock the NES Metroid, and Hard mode. And there are some Hard parts in Normal that are going to be Near impossible in Hard mode. Also, there is a gallery, and new pictures are added based on time and how many items you get. EG, theres a different ending if you get less than 15% of the items in under 2 hours beaten. Thats pretty much the bare minimum. If you do that on hard mode, you are a master
