the wiimote doesn't point directly where youre pointing at, it's slightly off, well, mine is- its close but not spot on.
They can always add a calibration tool for games that work in the light-gun fashion, Zelda:TP already has the option to modify the vertical height as to where the pointer is, I'm sure being able to get it spot-on is possible also.
Also regarding the controller shells, apparently Nintendo is packing the Wheel in with Mario Kart so it's not really much an expense since it's included by default, and the Zapper is being packed in with something as well which hasn't been announced yet.
Really? Damn, how'd they manage to screw that one up? Mario Party on the Wii has the potential to be the best multi-player game known to man, surely. :/
Fake-widescreen, graphics are essentially first-generation GameCube (it's as if the developers never heard of mipmapping), minigames are lame compared to the earlier Mario Party, the new boards aren't of much interest (to me anyhow), pacing is a bit slow due to unneeded special effects (or ones that could have been sped up a crapload), player animations are rough, hell, they even stop when they run out of frames during a "You Win" phase rather than repeating a standing loop. Overall, just really unpolished, even though some fun can be had if you can play it ignoring the above.
(I'm a real nitpick, although my sister enjoys the game a crapload)
