Great game, even if is not like other metroid games, this is a strong and solid action game.
From my perspective ( the one that is not from a fan of the series ) this is a very good game. It worth the money and the wait. it has great graphics to be in the wii system, but the strongest part of the game is the sharp controls, and the bosses. This game, same as Super Metroid in the super NES, was very addictive for me.
I had read a couple reviews from other players and briefly, they all complained that team ninja took all the great things from the series. Like i said before, i haven't played enough titles from the serie, so i guess that they all are right, but even if its not the same from the series this is a very solid and strong action game, actually is hard to find a good action game like this one in the wii system, i was expecting a longer game and honestly a little more challenging, Super Metroid wasn't an easy game for me, i was a 12 year old kid when i played this game, and i was expecting something like that challenging, and for that reason i believed that 8.5 is fair enough for this game.
To sum up, team ninja made a very good job with this game, if you havent play this game, you should considered, but maybe you should expect something diferent from the Metroid series ( i conclude this due to the reviews of the fans of this game, not from my opinion ) This game worth the money and the wait. Is one of the best action games that i had played in the wii.
