Awww, such a shame as it's my favorite gaming platform this gen (that I have, at least). I haven't even gotten to some of the best games yet, either like Fire Emblem, Majora's Mask, Kid Icarus: Uprising, Tomodachi Life and the Pokemons.
Totally agree that every single game would look better on the big screen and that my hands cramp like a mofo within minutes of playing. Doesn't take away from the amazingness of the games, though.
Maybe someday they'll make an adapter that lets us play 3ds games on the big screen. Until then, at least you gave it a fair shot and know it's not for you.
It'll be awhile before I figure out how to do one of these. :P
