#3: Professor Layton vs. Phoenix Wright
Huge disappointment. It was a decent game until the end, but the final hour or so ruins nearly everything good about the experience. The ending is so nonsensical, so convoluted, and so full of plot holes that it destroyed almost all of my enjoyment. Add that to the fact that Layton (at least in this game) is about as bland as protagonists get...and it definitely ended up being a disappointment.
#2: Mario Kart 8
Good game, really good netcode. I do have some complaints about splitscreen (you're really going to give us a touchscreen controller and not let one player use the touchscreen while the other uses the whole TV?), but it's a good, if not innovative, experience.
#1: Alien: Isolation
Not too far into this, but I'm enjoying it so far. What makes it genuinely scary is how little you see of your pursuer, making the moments where it does show up all the more terrifying. It's kind of like someone took the concept of the avoiding the SA-X bits in Metroid Fusion and made a whole game about that. I do wish it had gone with a checkpoint system instead of using manual save points, as those are somewhat easy to miss when you're concerned about a giant monster turning you into cat food, but Isolation is probably my favorite of these three nevertheless.
