Does Christmas count? If so, I got Mario Kart 7 and Assassins Creed Revelations :). Both are amazing games!
I've also purchased Harry Potter and the Philosophers Stone for PC as I had 1-4 but lost said game and the other day I fancied playing it :D
Not really a purchase but I received an original GBA, Super Mario World GBA and Tetris GBC as my Dads work colegue is moving to Australia and he's clearing the house out and gave us the old GBA :D. Not got my teeth into SMW yet but Tetris rocks!
On the 3DS VC i got Kirbys Adventure, Avenging Ghost, Donkey Kong and Super Mario Land. For DSi ware, I got Art Style: Kubos, Photo Dojo and Game and Watch: Helmet.
No full system games since OoT though.
