Okay, so I've had a New 3DS XL, my first ever handheld, for more than 3 months now.
I've played Monster Hunter 4, Ocarina 3D, Starfox 64 3D, Mario 3D Land, Resident Evil Revelations, Kid Icarus, and Ironfall.
But whenever I play, I just can't stop thinking "this would be so much better on a proper screen, with a proper controller". The tiny screen and the tightly clustered buttons and sticks just gnaw at me.
No matter how good the games are, I just don't think the handheld experience itself will ever be my cup of tea.
