EShop Titles I'd Recommend:
ZaSica's Last Stand (Tower Defender, High Score game)
Shovel Knight (Dark Souls the Platformer)
Neo Nano Assault (Beautiful, hard twin-stick shooter.)
The Fall (Story drive, short RPG. Very good.)
Pushomo World (Intelligent Systems... need I say more?)
Steamworld Dig (Another greatly built platformer.)
Armillo (Adorable.)
