They're remarkably pointless and annoying. Some people like to play their handhelds in vehicles, y'know. --- There will never be a game as horribly disappointing as Other M 3DS Friend Code: 2234-7169-9510
The fact you have to use the gyro sorta sucks if you're playing in 3d.
... but the whole point is to hold it straight and steady. so you shouldn't have to mess with the 3D angles.
Luigi seems to get knocked off balance with no gyro input at times (similar to things like thps grind balance etc. I guess) so requires some tilting to correct. It's hardly problematic. Just means the 3d goes wonky for a second.
I only hate it because if I'm playing while lying on my back, it makes me sit up to get across that part.
And the first few times, I was moving the 3ds back and forth too much because I didn't realize that if you hold it still, Luigi's pretty steady. I thought he's SUPPOSED to sway back and forth, and you have to compensate. --- sumuthergamer = some other gamer. Get it? Call me "gamer", not "sumu"...
I put my 3DS on a table and have Luigi tightrope it. As for D1, I went left right left right while running it to the other side, which actually worked. --- 3DS FC 1848-1670-8491 Luigi's Mansion Dark Moon pros only!
