I have Kid Icarus on the 3DS and Starfox on my N64. Is there a reason to get those N64-games on the 3DS? 
Not especially.
Ocarina of Time 3D is kinda neat though 'cos of the graphical overhaul. I prefer playing the original for nostalgic reasons, though. I heard it will also be getting a Wii U upgrade.
Star Fox 64 3D (what a bad title) I'm unsure about. I might get it if I see it for somewhere around $20, but the N64 game's not one of my favorites (far prefer the SNES original) and I have it on Virtual Console in 480p, so I'm good.
I just ordered it and won't be here till next week, but
Epic Mickey: Power of Illusion looks to be a lot of fun and I enjoyed the demo, so that might be one for you to look into.
I'm currently enjoying the pie-iss out of
Super Mario 3D Land. Best 3DS game I've played so far, topping
New Super Mario Bros. 2 and download titles like
Mutant Mudds,
Liberation Maiden, and
Mighty Switch Force! which are all great by the way.
AND LUIGI'S MANSION 2 IS COMING EVENTUALLY SO SAVE SOME PENNIES FOR THAT ONE 'COS IT'S GONNA BE THE BEST GAME EVER
