I'm thinking it should break 15M at the end, so I'll pick the positive range and 15-15.9 is my vote. However I wouldn't be surprised if it just about misses it.
As for the bonus; Probably Luigi's Mansion 2. One of the high point of the 3DS, which the best 3D effect on the system. I think 3 went on for just a tad too long. It was fun though and the characters were great. It's been too long since I played the original, it was back on GameCube, so while I remember I liked it, to my surprise actually, I don't really remember in what capacity.
