Conception II. it's really underrated, and it's a pretty good game. not great when compared to other JRPG's but it's good in it's own right. hmm, let's see.... then there's Shin Megami Tensei, but I believe someone else suggested that... Zelda OOT being hard though? I mean, it's your opinion, I respect that; maybe it's just easy to me because I have 95% of the whole thing (including Master Quest) memorized.... but back on subject. Metal Gear Solid 3 is on 3ds, controls suck without a CPP though. IDK if that matters for a N3DS... I thoroughly enjoyed my first twelve or so playthroughs of Bravely Default, and Dragon Quest V for DS is really good too. Fire Emblem 11(Shadow Dragon) and Fire Emblem 12(Shin Monshou no Nazo AKA New mystery of the Emblem) are Really good too, you'd have to get a translation for 12 though. and a Flashcart if you don't already have one. though, you could always just play FE12 on your PC.
