By the way, all we play on my console is MK8. We beat NSMBU really quickly with the Boost Mode crap, though we didn't get all the big coins and beat the bonus world. We barely did any SLU. I had SM3DW and DKCTR but we played them maybe 5 times combined, so I traded them in to Wal-Mart for more than I spent on them. I also got Wind Waker HD as my free game with MK8 but I've played maybe half an hour or an hour on it (just to the part where you're about to leave the island, I think). I just am not big on the franchise, and it starts REALLY slowly, so I struggle to play it.
As for the future, SSB or bust. I might pick up Bayonetta 2 because it comes with the highly regarded first game (which I've never played). I MIGHT get Toad Treasure Tracker (out 12/5/14) because it's only going to be $40, rather than $60. Next year, we get MP10 and Yoshi's Wooly World, which will be a great pair of additions to the lineup of games.
Lastly, on a long-term basis, I'm begging for a console Fire Emblem to come back. GameStop wants $65 for Path of Radiance from mid-2008, and eBay is not much better ($45 for game only), and I can't bring myself to pay $15+ more for a game than it cost at launch so long ago.
