Are the Wii controllers unique and different, or are they better?
unique, definitely. different, of course. better? depends. Personally, I found the sword slashing controls in Zelda sometimes a bit annoying to be honest, at times I would rather just press a button. (and do, there are a couple of sword moves that can be done just with the button) othertimes though, it does become kinda naturally to shake the nunchuk to get rid of an enemy that caught and bites me.
You made a comment essentially saying that FPS are boring and generic and having to learn a new controller scheme makes the games different and therefore better.
Can't really comment on that since I haven't tried an FPS on wii yet but it's certainly possible. Some reviews seem to point to that too, for example see gametrailers.com video review of cod 3 for wii.
But is that all that it is? Is it just that you had to 'rrelearn' the controls in order to play? OR are the new controls better than the old?
again, being better or not depends on the game and the implementation. I guess it's widely accepted that Madden 07 for wii has better controls on wii than on other platforms but I haven't tried it yet so can't really comment.
What is better is definitely some of the wii sports and wii play titles. Bowling for example, I couldn't imagine getting into the game like that with any traditional gamepad or mouse/keyboard combo. Best example IMO where they really nailed it is the 9-ball billiards controls in Wii play. Now there's a game I would really pay more money to get more depth to the game. The aiming and hitting really make it the best billiards game ever, even as it is. Now if there more gameplay modes such as tournament / ranking gameplay, online multiplayer and most importantly less square, maybe longer table, maybe option to play snooker instead, I could easily see myself playing the game quite a lot more. As it is, its a nice demo with very best controls in a 9 ball billiards game ever.
And if its just different.... doesn't that lend itself to open up totally different debate about difficulty levels and whatnot?
In the cases where it's just different, well I guess game developers can come up with a good compromise on proper levels of autoaiming and such.
I guess the worst thing in the wiimote is the omission of another analog stick. Now if there was a dual analog wiimote, the issues of turning in fps games would be just gone. As it is though, we're back to single analog stick control compromises similar to N64 games, with a couple of tweaks that come with the motion sensing tech, still making turning fast enough quite clumsy, so far I've heard.
edit: speaking of another analog stick... it wasn't until third temple in Zelda when I realized how well the camera angles in the game actually mostly worked. Before that water temple thing, I hadn't even noticed I hadn't been manually adjusting the camera. Then when diving deep in a pool there I realized in that case it would have been helpful to adjust the camera but I couldn't do that since the other analog stick just isn't there
