So I started playing Metroid Prime (Wii Trilogy version). I'm not very far into it yet, but Retro Studios definitely got the atmosphere down. I never experienced the GameCube version, but even over seven years after its original release, the graphics and audio hold up quite well.
The Wii Remote controls are pretty nifty, though again I don't know what it was like on the GameCube. This is the first "FPS" I've played on the Wii, and comparing this setup to a 360 controller, I wouldn't say this is more accurate necessarily for precision shots, but I do feel like I can track enemies more quickly and naturally. My experience with traditional gamepads with this genre is not that great either, but it usually feels clumsy and disconnected unless I'm sniping. Being able to point with my wrist, on the other hand, it's very easy to zip (roughly) in the direction of the target. The enemies I've faced so far haven't really had "weak points," however, and I suspect the hard part would be trying to focus in and keep it steady on a small target.
What I don't so much get is the scanning mechanic. It seems very tedious and cumbersome having to constantly scan everything, especially since you have to turn off your cannons and manually activate scanning mode just to see what you can scan. I'm not even sure why I'm scanning these things. It certainly doesn't make any narrative sense for Samus to have to take fire without responding for several seconds so that she can download some mostly irrelevant data on an aggressive hostile. In a lot of other games, enemies just get added to the bestiary after you defeat them. In this game, it seems as though I seriously spend more time scanning than doing anything else. I guess that's what it's like to be an explorer, but I thought I was supposed to be playing a bounty hunter. Am I just not getting it?
