Alright, I just put about an hour into the game. Here are my impressions.
Graphics - Very good for a Wii game. I'm not as adept at picking up the difference between 30 & 60 fps, but this is very smooth. The environments look very good so far. It's really nice to see Samus' suit again and as good as the Retro games were, I really like her model in this game. It looks much better. Also, the game has a certain arcadey vibe to it, much like F-Zero GX and the opening level of Star Fox Assault. The cinematics are also very well done. The game is very fluid and the transitions between first person and the cinematics are extremely smooth. I haven't had one load time yet and the game has probably split between cut scenes as well as different levels at least twice. There are some jagged edges present as well as some low textures, but this is a Wii game we're talking about.
Gameplay - I'm surprised that I'm complaining about this. I really want to like it, but there are a few things I just can't get past. First, the d-pad on the Wiimote is tiny. I don't think I would mind using it if it were the size of the d-pad on the classic controller. The next problem is pointing at the screen. I works really good for looking around a room, but not for precise aiming in the middle of the action. Think about how slow paced the Prime games were and think about how fast paced Ninja Gaiden games are. Now imagine having to switch back and forth between the two. It's a terrible design choice, perhaps the worst one in the game. Like I said, it works well for looking around a room, but the only way you can use missiles is in first person. They really should have used the nun-chuck in this game. It would have solved so many issues. Lastly, I will give some praise. This game has opened up a whole new mechanic that needs to be explored. I really like the seamlessness of the combat. Everything is extremely smooth and polished. Finishing an enemy, dodging and aiming are all new ideas. It really is the first game I can think of that has combat like this. It's an interesting twist, but it really speeds things up. If they could only fix the controls, it would be a much better game. Instead your crippled with only using the Wiimote.
Story - A lot of people have complained about this but I don't find it quit as repulsive as some have made it out to be. Anyone who has followed the Metroid series knows that they were leading up to some major details of Samus being revealed. We have finally reached the point to where those details are revealed. So far, it's not what's being done to Samus as a character that's most disappointing, but the way they did it. There are times when I just want her to shut up. Whenever she first landed at the space station she didn't say a word. I suddenly felt that sense of isolation that makes her feel like such a badass. Then, she opens her mouth. Uhhh. It's not even the fact that there are other humans involved. I just wish they wouldn't have given her a voice at all except for in narration. They could have done it like they do in the Zelda games where the character doesn't talk. Here's an example.
Samus: "I'm here because I responded to a distress call."
Or
Adam Malkovich: "So Samus, I guess you got the distress call too."
Both ways tell you why Samus went to the Space Station except one retains that sense of mystery behind the character. Anyway, there's a lot left to the game for me to explore, but I feel like the series is slowly losing what made it so great. Hopefully they can fix all of this because I feel like if they took all of the best elements from every game up until this point, they could make the ultimate Metroid game.
