I didn't play my 3DS much last year, but this year, I played Phoenix Wright: Dual Destinies and absolutely loved it. One of the best of the series even if I did miss examining things in the investigation period (besides the set periods where you can).

I also so got back into Pokemon and bought Pokemon X. I'm not so far into it (just past the first visit to Lumiose City) but I am loving it so far. It takes a damn long time for a perfectionist like me: so many Pokemon to catch and level up, not to mention super-train.
