I think some motion games like dancing motion games maybe popular with some mobile gamers who play games with a large tablet, and the webcam on the tablet is use for controlling the game.
But, I feel motion games which require a lot of jumping, hand waving, and weird hand gestures maybe less popular because they look kind of weird to play in public.
Racing games where you steer the car by turning your phone to the left and right to turn the cars are popular with some people.
Nice discussion. I do think that it would be since a lot of people are using mobile than pc... so yeah I agree with you that it's kind of not cool when incorporated on mobile but I will stay optimistic about it <3
I feel there maybe tablets with motion controller remotes which are similar to the Wii, and Switch motion tv remote style controller which is used for playing motion games like bowling, tennis, and boxing.
But, I think the motion games for mobile devices would need to be playable while people are sitting down closer to the screen of their tablet because many people use their mobile devices while sitting down on a chair.
