Vast majority of games aren't.
And then you have the Virtua Fighters and the Hearts of Irons and so on.
Hearts of Iron is basically a EU: World War 2.
My point is that games are entertainment first and foremost. You probably can't create a twitched base Quake 3-like gameplay for it, but it doesn't necessarily make games for it unenjoyable - they might be still very pleasant experiences despite not being as complex as Europa Universalis. If someone says that Kinect in principle can't have good, engrossing games, than I at least hope he plays the most hardcore games exclusively.
