Metriod Prime is boring, easy (my 5 year can get %25 of the way through before he too, gets bored), it does NOT capture the feeling of metriod to any degree. Its lifeless, it feels more barren than any other metriod, like not only are you the only person on the planet, but it feels more like you are the only person in the universe, just utter solitude.
The "bombs" when your in a ball (if you can call them bombs) only let you drop 3 at a time, (with a long delay before you can drop them again) so the funnest part about metriod games (bombing up to where you shouldnt be yet!) is completely removed.
You find yourself holding the L button for the entire game.
The whole "exploration" thing, which metriod games thrive on, is just....not there. Its pretty linear, if you dont know where to go, well wait about 30 seconds and the game will show you on the map, and you pretty much cant go anywhere else. They lead you by the hand every step of the way.
But dont take my word for it, it got very bad reviews in most of my game mag subscriptions so read those, they basically say exactally what I did.
And I am a HUGE metriod fan, I love Metriod, Metriod 2 return of samus, Super Metriod, Metriod Fusion, and Metriod Zero Mission, but metriod prime is just a let down and I wont be buying Metriod Prime 2.
