This is a real beauty that has become so misunderstood of all time. Two common myths figured around this little cube when it went. It was said that it was the least powerful of the consoles for generation and that it had no games. Both rumors were false.
Nintendo GameCube was his generation's most powerful machine and deliver graphics that really makes the competition to shame. It is also small and stylish! Supports game up to four players on the same console, but there were also options for connecting multiple consoles and thus increase the number of players.
Cube use out of 8 cm mini DVD discs, which means that the loading times shortened somewhat extreme, which stands out even against today's generation. Spar connections are made on the memory card, smoothly and easily.
Moreover released very many great accessories. Eg. DK Bongos controls that are designed as bongo drums and used for some Donkey Kong games, music game Donkey Konga. Or the Game Boy Player, which allows one to play all Game Boy games on the TV screen. It is also possible to connect the cube with the Game Boy Advance, which is used in several games in innovative ways, very fun to experiment with.
The major drawback with the Cube in comparison with its competitors, however, was that so few games had online support.
But what makes a console, the games are available to it and the Cube, most third-party games that were released during generation, plus a large library of first-party and third-party exclusive games. There are a lot of games that make the Nintendo GameCube is a must in any gamers console collection:
Donkey Kong: Jungle Beat (use the DK Bongos controls which works absolutely heavenly!)
Resident Evil (remake exclusive for the Cube and the best Resident Evil game ever!)
Resident Evil: Zero
Eternal Darkness: Sanity's Requiem (Psychological horror, a little Lovecraft preferable)
Kirby Air Ride (Extremely simple controls but so extreme fun too)
Soulcalibur II (With Link as a playable character!)
The Legend of Zelda: The Wind Waker (Now also available as an HD remake for Wii U)
The Legend of Zelda: Twilight Princess (Available also a Wii version with motion controls)
F-Zero GX (Have not yet have a sequel!)
Beyond Good and Evil (Available to competitors, but this is the best console!)
In addition we Game Boy Player'n which makes it possible to play the entire Game Boy family (ie Game Boy, Game Boy Color and Game Boy Advance) wonderful titles on the big screen, and in combo with the official Gameboy Player Controller from Hori will be it's unbeatable!
Sure you could buy a Wii and play GameCube games on it, but then I would recommend that you instead buy a Wii U (Wii games) and a small cube. You can not use the Game Boy Player'n on Wii't!
