The fancy no-glasses 3D tech Nintendo's latest handheld is packing comes with a few caveats, one of which is the fact you have to try and keep from having the thing shake while you're playing it.
Because the 3DS' effects are only workable if you're in a viewing "sweet spot", you've been reminded that any sudden movements can cause "issues" with its 3D effects. That warning, by the way, comes not from a sterile Nintendo legal document, but some Tweets from Kid Icarus director Masahiro Sakurai.
Keeping the unit steady may sound ridiculous, but it'll be a concern to people playing on public transport, especially buses. I remember when I used to catch the bus in Sydney and on a busy morning I'd have enough trouble hanging onto my DS at all, let alone keeping its screens still!
