3DS Game Recommendations

[Majora]

I'm trying to still convince myself I didn't waste $200 on this New 3DS XL so I need recommendations. Not JUST 3DS games but anything this thing can play.
Games I +have or am -planning on getting

+Smash Bros
+Monster Hunter 3 Ultimate
+Shantae
+Shantae: Risky's Revenge
+Golden Sun: Dark Dawn
+Mighty Switch Force
+Mighty Switch Force 2
+Mario Kart 7
+Soul of Darkness
+The Legend of Zelda: Phantom Hourglass
-Hyrule Warriors maybe, if I'm drunk enough when it is released on the 3DS
-Cave Story
-Swords & Darkness
-Zenonia
-Shovel Knight
-Every Zelda game
-Any one mario game (Need a recommendation)
-Any one pokemon game (Ditto)
-Shantae and the Pirate's Curse
-Fire Emblem: Awakening

Note the word is games. Which means Animal Crossing and Tomadochi Life is disqualified.

Oh right: no lego games or games that exist on other consoles (I have seen some games in the 3DS shop that are from Wiiware on the Wii, for example. I can just pirate those). Games from retro consoles are fine (e.g. Megaman 2, Zelda II, et cetera)
