I have to say, none of them! They never made any games I could truly love on Kinect, except maybe Fruit Ninja? But I don't think that can be made better much, it was pretty good on the 360. I never played Kinectimals but similar gameplay is being tied into Zoo Tycoon, so I guess I hope they improve it.
I never got my Halo Wars and Viva Pinata Kinect :(
I hope you get them this time. After playing 'Tower of Bable' I don't think Kinect 1.0 is quite sensative enough for something like Halo Wars. I hope you get them this time on the Xbox One.
You should try 'I am Super' from Kinect Fun Labs, and Kinect Party. Not games so much as funny experiences + strongly suggested you play them with drinks or children (or people acting like children.)
Since you weren't that please - I hope this helps. Here is your Ice Cream!
