Nintendo starts things off with a bang today with two high profile titles: Liberation Maiden (3DS eShop) and NightSky (3DS eShop) -- expect our reviews soon for both. For the 3DS Virtual Console, there's Ghost'n Goblins (eShop VC), and Castlevania: The Adventure (eShop VC) should you feel nostalgic.
18th Gate (DSiWare) and Shock Troopers (Wii VC) are also launching today, if you have any money left after spending it on the above. If you're flat broke, there's also a free Marvel Pinball 3D demo and an update for Mutant Mudds (!) that adds 20 free bonus levels.
In terms of DLC (which is still weird for me to say, "Nintendo DLC"), New Super Mario Bros. 2 gets two coin packs -- the "Gold Mushroom Pack" and "Coin Challenge Pack B" -- the same packs Japan got today.
