Sorry to hear you're not enjoying it as much as we are.
I think you are wrong in your assertions. In my opinion the games are more accessible and much more fun because they aren't using a modern controller.
I'll paraphrase something I read a while ago:
Gaming is a great example of this.
Consider what many of today's gamers grew up with:
Pretty accessible and didn't really limit people having fun.
Fast forward to today, the modern controller has an 8-direction dpad, 4 face buttons, three system buttons, two bumper buttons, two analog control sticks, two stick buttons, two analog triggers, at least 4 lights and (in the case of Sony) pressure sensitive face buttons and motion sensing. 17 buttons and 6 analog axis.
When being fully utilised a modern controller is utterly and totally inaccessible to anyone who didn't grow up with gaming. Even one button+stick games confuse people (pressing wrong buttons, etc)
So here we have Kinect, which I'd argue is the most accessible piece of technology in history.
It's also amazingly precise (considering what it's doing) and robust (also considering). With it you can do more than the Atari joystick above - even JoyRide demonstrates this (boosting, grabbing, drifting, etc).
Combine these things, and suddenly a huge chunk of the world can now approach gaming and
understand it. And have a hell of a lot of fun at the same time.
People are enjoying the games, even if they are very simple. Just like people enjoyed Atari games and earlier. But now there is an added level of immersion and far less abstraction because you are using your body - which means it's more fun.
... I could go on but writing this is irritating me. It has made me remember how tired I am of 'core' games. They aren't really fun anymore.
