I noticed this when playing Zelda OoT. During a boss fight, I'd have to pause the game and reposition my thumb on the analog stick to make it not slide off. On top of this, after walking around a bit, my thumb gets really sore. It hurst my finger to an extent that I don't find playing enjoyable anymore. I asked my friend who also has a 3DS and Zelda. She said "Yeah, definitely", almost before I finished the sentence. Does anyone else have this problem? Edit: The title of the thread is plural by accident, but I suppose I can't change it anymore.
