Expecting a fast paced first-person shooter, this game will let you down. Expecting puzzle solving adventure? awesome!
I went into this game with the wrong expectations, I was fired up at the thought of an action packed contra-esque Metroid game. Why I expected this, I don't know, we've all obviously learned by now that Metroid is not about the action. The result of my wrong expectations was boredom, when it got to the somewhat slow parts of this game I lost all motivation to continue... I wanted to shoot more things, I wanted to quickly gain new abilities for my awesomely powerful Chozo suit, and this button after button to open new doors thing was taking too long.
So I cut loose from playing it and enjoyed some Mario Galaxy. I recently went back to Metroid Prime 3 however, now with the appropriate expectations, and I'm happy to say that this game is awesome and my favorite Metroid game to date. Even going back to the SNES days. I still find myself hungry from time to time for more action and variety in enemies, but I think that is the side effect of the amazingly intuitive control system... it just makes running and gunning sooo much fun, whenever you enter a room where you get to battle multiple enemies or even to a boss fight, it's a huge treat because of the weapons and abilities at your disposal and the ease of which you can access them all.
I'm fired up to see other games copying this camera and control technique because it is by far the best ever for a FPS style game on a console. But I don't think I'd call this a FPS so much as an FPA, first person adventure. Get ready to go back and forth between worlds to solve various problems, get ready to drop what you're doing and head back to another level because you forgot one tiny detail... as long as you're ready, this game will give you a one of a kind experience that will stick with you for a long time.
