Had my 3ds since launch, and have mostly been playing with the 3d off, since it wasn't too impressive to me. However when I picked up Ocarina of Time 3d today, I was REALLY impressed by the 3d in it. Definitely the best the system has to offer so far. While I really enjoy playing the game in 3d, is extremely annoying because I have to remain perfectly still while playing. Any slight movement and the 3d effect is ruined. Sadly, its just easier to play with the 3d off, because then I can actually let myself become immersed in the game, instead of constantly trying to maintain the correct viewing angle. Personally, I find that I lose the effect maybe about once per minute, because I just have trouble holding the darn thing still. I'm curious how well its working out for the rest of you guys.
