Easily the best FPS on the Wii, ever.
I normally play many games just for plot, but in this game, I had so much fun shooting I barely noticed it. One thing that was odd to start with is that A is the firing button, normally a jump button. While B is jump, reverse of A. But in retrospect, I think that saved me weeks of carpal tunnel.
Shooting is a dream. The accuracy is much more smooth than any other FPS on the wii. Best part is that if the crosshair ever moves off screen, instead of dragging (like in Red Steel, COD 3), or stopping the whole game (Zelda), it conviently stops moving, puts up a yellow sign indicating there is no crosshair, and continues the game, allowing you to re-aim the crosshair without stalling the game or being dragged into a point where recovery is target practice for enemies. To be honest, I think the crosshair only moved offscreen 5 times, throughout the entie game. It's that smooth. As opposed to Red Steel, where my crosshair moved offscreen if my arm moved an inch.
The graphics are amazing. I know the graphics are "Last Gen" hardware, but this game really pushes it. Samus' ship is as beautifully rendered as she is. And her weapons couldn't be shinier.
Unfortunately, the morph ball still feels a little slippery on the control. I know inertia makes sense, but even on the side-scrolling morph ball stuff I had to redo careful moves a few times. But that didn't take away from the core game. I was disappointed with the lack of multiplayer, and would honestly pay a full price for a game that was just Metroid 3 multiplayer, as long as it contained online.
Boss fights are a blast. Loved how creative the boss designs were, as well as the fights that followed. Every weapon was creatively used, and I enjoyed fighting them.
Metroid Prime 3 is a great game, and if you have a Wii, you need to get it. If you don't have a Wii, steal it from that guy you know who got a Wii on release and lords it over everyone else you know. Yeah, take it from him, and enjoy Metroid Prime 3 for as long as you can.
