I never use it

its good in zelda LBW.

personally, no! i find it headache inducing if anything and never use it. but i'm also sensitive to certain motion so that might be why

its neat, but not really essential. if you use it too long, you will get a headache lol

i main my 2ds xl because i see the 3d feature as a gimmick ill never use

It's a very cool feature that's only beneficial in very few games. Infact, if you mostly play non-3DS games on the thing or want to play Pokemon, don't buy it.

its very useful in super mario 3d land its harder without it and in other games its kinda cool and it doesnt make me get a headache but ive used new 2ds xl and new 3ds xl and the new 3ds xl also just feels nicer and higher quality
