if you like a great science fiction game that makes you think instead of chaoticly . If you want a game that is better than halo. If you want to be totally blown away, buy metroid. This game is competed with Half-life 1 and 2 in my book. Metroid Prime has a great story that you end up with more questions then when you started. It is also a continuation of the old metroid games which is always a plus. Gamecube may not be the best system but it's got one of the best games. It has a very good ending, and I play the ending over and over.
