Why It's Great: While previous handheld Metroid titles delivered console-quality 2-D adventures, Nintendo took a real risk adapting the Metroid Prime series to the DS. Thankfully, the company succeeded. The game is one of the nicest-looking DS titles, and the gameplay emulates its GameCube predecessors quite ably. It's more about one-on-one encounters with other "hunters" than the puzzles from previous Primes, but the fast-paced action fits the DS better. Also a good fit; voice-enabled online play, which no other Nintendo title — console or portable — supports.
