I took advantage of Target's Buy Two Get One Free sale. I bought The Wonderful 101, Rayman Legends, and Pikmin 3. There's a really good chance that The Wonderful 101 is the only game I keep. Pikmin 3 will be switched out for The Legend of Zelda: The Wind Waker HD in a couple weeks and I'm on the fence on Rayman Legends. I thought I only had 30 days to return or exchange, but I have 90 days (until 12/21/2013) so I may switch that for Super Mario 3D World. I don't think I have time for more than those three games so New Super Luigi U, The Legend of Zelda: A Link Between Worlds, and Donkey Kong Country: Tropical Freeze will likely have to wait until next year.
Mutant Mudds Deluxe is on sale on the eshop. I was thinking about downloading that.
EDIT: I bought Mutant Mudds. With the left over eshop money I had on there, the rest was less than $5. Tough game.
