Obviously I don't care what anyone plays it on and if you prefer it without 3D that's fine, I just really don't understand how people seem to have such a difficult time with it. With the sheer amount of people I meet who have so much trouble with the 3D I feel like either everyone took literally ten seconds to try to figure it out before going all old and "grarh this newfangled whirr-sprocket gizmo is terrible!" or I'm some kind of god at using it.
I've used it for around an hour with both Pokemon and ALBW. I'm more interested in the gameplay, I didn't find the 3D to be much more than a gimmick. There's probably games out there that capitalise on it more than ALBW does, but I'm not really interested in them.
Even with the small screen on the 2DS, ALBW looks very pretty. The only thing I'd get the XL for is the big screen, which is great, but I found it to be a tad dimmer than the 2DS because of the 3D feature.
