Besides Smash, I've played two, both very good.
Bayonetta 2 is fantastic, my personal game of the year and new favorite action game of all time. It's cheesy and over-the-top fun, with some of the best combat you could ask for. Can't recommend it highly enough unless you just don't like the genre at all.
Donkey Kong Country: Tropical Freeze is also a very strong one for its genre, with some great level design and fun boss fights. Plus, Cranky Kong is basically Scrooge McDuck, which is great.
I've also heard that Pikmin 3 and The Wonderful 101 are very good, but have yet to play them.
