I'm pretty happy with the latest sequels/remakes/reboots of the classic Nintendo games. My girlfriend and I just beat New Super Mario Bros. which was a perfect game, on par with the classics and even better in some aspects. We're now playing through Donkey Kong Country Returns, which is just as good though shaking the wiimote gets annoying sometimes. Metroid: Other M, as far as I played, was okay. Not classic enough for me, but close enough for a new take on the series, I suppose. Kirby Epic Yarn is great so far, too.
Even Epic Mickey is good and brings back memories of Magical Quest. I was impressed that it was a solid game, to be honest. Disney's games have been slacking in the past decade or so.
