Haven't played mine in well over a year. Sold almost all the games I bought for it.
Even if I wanted to play on right now, it's extremely difficult because the HOME button is broken. I can't play without the system plugged in, because the battery can't stay on for some reason.
Man, I hate the 3DS hardware so damn much. The features are worthless gimmicks, the screen and specs were insufficient from day one, and I've had button failures and other issues on two separate devices.
I put up with because of the many great games on the system. I had some wonderful experiences with games like the Etrian Odysseys, SMT IV, Animal Crossing: New Leaf, Kid Icarus: Uprising, Fire Emblem Fates: Conquest, and Monster Hunter 4: Ultimate.
I do regret not playing a few of the games I sold, including SMT IV: Apocalypse and Dragon Quest VII, but I'm done with 3DS and never going back!
