Professionally, I'm fascinated by Candy Crush and similar F2P games. But as a consumer, this kind of thing is just as appealing (link). 

It's interesting to see how new input methods and devices shape new game types, as do business models (very obviously in the case of Candy Crush). My colleague Chris Dixon, who's used Oculus, tells me that using a first person shooter in VR could well be problematic - it's just too real.
