I've only spent ~10 minutes playing a few AR games, but I did get slight headache from playing it. Although, that was most likely from the pain the screen caused my eyes (I guess this goes under eye strain). It took me quite a bit of time to adjust. Movies aren't as bad as it's a passive thing, but I haven't done any type of 3D with games before this.

I tested one today. I just see 2 images and sometimes those are blurred together. I think it would give me a headache if I used that for long, even the short (5min) test period made me feel uncomfortable.

When I closed my one eye, I could see only one image but I don't think it was 3d. :P But no discomfort there.

been goofing around just admiring the menu stuff, the mii plaza looks AMAZING

had fun and laughed my ass off at my face raider face

the ar game played for a bit and was pretty neat, though more excited for future when the viewing range can be farther away.  i think i just need to play on different surface.  was on pool table and got a stiff neck/back having to lean over that much playing

no games yet, so maybe that will change.   BUT as of now, no side effects at all, no head ache, eye strain, dizzyness, ect.  I can see the 3D great, and even have the slider all the way up. 

So no negative systems from me, and can finally vote

and where are all the comments from the 95 yes'ers?  i want to see your "i picked it up at best buy for a minute and it hurt"  comments.  Cuase i'm just fascinated how almost half the people seem to have headaches.  i have yet to find someone in real life that has had any headache, eye strain ect when i let them try mine out.

yes - 95

no - 126

No negative affect while playing ssiv for an hour and 15 mins on the bus. Though it felt weird when looking at the text in my book... I don't seemed like the words were still popping out of the book as if it was in 3d.

And I wouldn't give out my friend code to people on the internet.

Had today off, so I marathoned this thing. AR games, Face Raiders, Camera, SSIV, Steel Diver - at least 6 hours worth of play today with no negative symptoms. I'm sold. It sucks for those who do have negative symptoms, but I'm still convinced it is much less widespread and serious as the haters would want us to think.

I take it back, I got dizzy after spinning around playing Face Raiders for like 40 minutes. HA! Still fun as hell though!
