After 100%'ing the game I'm torn, as many of you seem to be.
I had a great time with the action; running, shooting, and yes, shooting in First Person as well. For myself, the way Samus moved was what felt the most satisfying to me throughout the game.
As a compliment to that, I loved the camera perspective changes as you would run through an area and switching into first person with the Wiimote was easy and fun for me.
I enjoyed the boss encounters as well although I thought they could have been much more difficult...........perhaps bosses where you had to climb them to get to their weak spot and pull off some damage. More cinematic interaction if you will.
Now the rift.
While the graphics look good in many places, the textures (especially in the Arboretum and certain rock structures in the Lava area) were atrocious and painful to look at. Also, going through the art gallery and comparing those images to the actual rendered environments, so much personality was lost in translation. When I was looking at the art I thought "So THAT was what they were going for there!", in game however, only a small handful of the environments came across as moody, with impact, , or even interesting and memorable.
Why get missiles and accel charges later in the game if there is nothing to fight except the final boss? This is a slightly complex issue with the game design because if I had been able to recharge faster, earlier in the game, the game would have become even easier. But I feel it is much more fun to charge faster, and I would have liked harder enemies, or even any enemies to fight at all with all my powerups.....it feels useless to even have 80 missiles and be able to charge up quickly.
So I started Hard Mode. No powerups at all? That's frustrating/unfun mode.
So, while it is fun to control Samus during the main story, I feel this turns against the game towards the end since you have a boss and some marginally tough insects (powerbomb doors) to fight (until you figure out the best way to take them down) and then a whole lot of missiles, a fast charge, and nothing to see, do, or discover.
For the first time in a long time, I feel that I bought a game that would have made a very fun and fulfilling rental.
I didn't touch on the story because enough has been said about it here. Everyone will have varying opinions based on what they know and like.
Also much has been said about the over the shoulder sections. Boring? Sure. Broken. No. Unnecessary? Probably.
Where's Waldo........pointless and misguided.
7.2 for the number lovers ;-)
