So I took the bait in the end and tried this out, with the cardboard gizmo. It's true that you can only play in short sessions, but for me it was not the eye strain, but the nose! Holding that thing on my face, whether sitting or laying down, left it matching the console in color, ouch.Getting more and more tempted to buy it myself for the same reason, even though I know it'll most likely end up gathering dust. Damn you Nintendo, for knowing how to get on my weak points.
Tried a bit all of the games & my favorite have been Innsmouth (though damn it's stressful) & Red Alarm, the 3D is great on that one.
What they all have in common is that they're very difficult and beat my ass in seconds (other than Wario Land, that's more manageable but haven't played it much).
What else... Played Mario Clash for a few levels & the buttons are switched, I kept pushing the wrong one all the time. I know this can be changed but never bothered because I'm lazy or stubborn or both.
Neat curio, 3D is very crisp and clear, and will be playing more. Gotta find a more comfortable way to play it for longer periods, but can't think of one (the original of hunching over a table doesn't sound very appealing either, even if I could do it with the expensive device)
