Sell me a 3DS - I need 10 Exclusive Must Have Games

[Mnementh]

Kid Icarus: Uprising
Etrian Odyssey
Fire Emblem
Dillons Rolling Western
Freakyforms Deluxe (really, it's a great game although it looks strange)
Denpa Men
Heroes of Ruin
Pullblox and Fallblox (named Pushmo and Crashmo in the US)
Bravely Default (it have to come to the west)
Code of Princess
Project X-Zone
Pokemon X/Y
Hana Samurai (heard it is named Sakura Samurai elsewhere)
Crimson Shroud
Liberation Maiden
Luigis Mansion: Dark Moon

 Technically Monster Hunter (also WiiU) and Zelda:OoT (N64) are not exclusive. While I prefer MH on home console I recommend Zelda for 3DS. Edit: i see you own no WiiU, so you should get MH-greatness on the 3DS.
The excellent Resident Evil:Revelations will come to home consoles, I recommend to get it there.

Edit: The XL is worth it. In europe it comes without the power cable though, that must be purchased separately or taken one from DSi or DSiXL (they are the same).
