Best Buy was having buy one get one 50% off select Nintendo games last week, so I picked up Super Mario 3D World and The Wind Waker HD. Spent about $75 after reward certificates, so not a bad deal at all.
Bought a few games over the holidays. I picked up Tomb Raider for PS3 a few weeks ago since it was cheap at Target, got Luigi's Mansion: Dark Moon for Christmas, and bought The Legend of Zelda: A Link Between Worlds on Saturday. I also have added a bunch of games to my Steam library through the Steam sale and other various sales: BioShock Infinite and Brothers: A Tale of Two Sons from GameFly a few weeks ago, and I've gotten The Stanley Parable, Game Dev Story, Mark of the Ninja, and Bit.Trip Runner 2 from the Steam winter sale, as well as the season pass for BioShock Infinite.
I picked up "The Legend of Zelda: A Link Between Worlds" on Boxing Day. It wasn't on sale, but I wanted to play it and I had a gift card from Christmas
Picked up a few games on my excursion into town this past Saturday: - Star Fox Adventures (GameCube) - Splinter Cell: Chaos Theory (GameCube) - Trauma Center: New Blood (Wii) I also pre-purchased Assassin's Creed: Liberation HD today on Steam. Kind of nervous since it's my first time playing an AC game on PC instead of on consoles, but hopefully the game is good. The demo I played on PS3 seems decent enough.
Mario Tennis: Open! I love me some tennis, so Mario + tennis = instant buy. I had been waiting for a good deal before going for it and finally got it for around $25 on Amazon awhile ago.
Picked up Pokémon Platinum today because Geoff keeps saying it's the best Pokémon game. >:| Also, Final Fantasy: Crystal Chronicles.
The last few games I bought were Symphonia Chronicles the other week and then today I picked up Professor Layton and the Azran Legacy. ♥ I'm hoping the latter is damn good. I expected to pay lots for the former because it was the Collector's Edition but the latter was over $50 because I didn't want to find it online and wait for shipping and everywhere in Canada has started selling games for at least $5 more than usual. ;_;
I pre-ordered Deus Ex: The Fall on Steam, as well as Metal Gear Solid V: Ground Zeroes, if those count.
Been giving my N64 some love this week - got Diddy Kong Racing from eBay, and then picked up Tetrisphere, Star Wars Episode I Racer, and Donkey Kong 64 along with the Expansion Pack from a local retro game store.
