I'm with Yahtzee all the way on this one. I'm afraid i don't see motion controls as more immersive. If anything, i feel it detracts from the experience. I don't want to wave my controller about and hope my avatar picks up on my vague commands and swings a sword or what have you. There are three stages to interaction. Thought, command, response. The user must be able to issue a command with minimal hassle to gain a fast response. With a button press, assuming the user is well-versed in gaming, the time taken to press the necessary button can be less than a second. But with wii-mote flailing, it can take up to one or more full seconds just to issue a command. This is unacceptable and takes you 'away' from the experience. It feels unresponsive. There's a certain zen-like nature that comes with traditional button controllers that you just can't achieve with motion controls. I do, however, think motion controls will become standard in future consoles and games as Moviebob says. I do not think it will replace traditional methods of control, however, and will be there as an optional extra / peripheral.
Great article / discussion / column / thingy, but please make it longer. As someone above me said, it came off as half transcribed and unfinished. Almost like no-one was really able to come up with a counter to Yahtzee's retort about motion controls not quite being as immersive as traditional control. I'd really like to hear some rebuttals on that. It would have been good to see more input from James, as it felt like he was drowned out by the debate between Yahtzee and Moviebob. I expected something more insightful or more substantial from him.
