You highlight a very important difference between the media, which is that television is basically a disembodied experience for the watcher, while video games are putting the player inside the frame somehow. As Keough points out, mastery of the controller is essential for forgetting its existence and merging with the experience, just as learning to choreograph turn signals and acceleration and breaking and steering and mirror checks and road-sign comprehension into a singular activity (part-to-whole gestalt formation) is essential for a driver merging with their vehicle. Mobile phone games have the simplest interfaces yet, so you see them everywhere that people are killing time. I suspect that immersion isn’t less for video games, but that the level of immersion they give already—a level similar to TV—is already sufficient, and so the VR headset tech and funky controller technology is excessive and unnecessary for the experienced gamers they were marketed to. Since games do need some kind of embodiment, though, the shape and form of that relation is everything. (Remember the hype over “hand-eye coordination” which video game controllers bestowed upon youth, as though that was some kind of particular, generalizable gift? Did all the kids who played Mortal Combat become expert whittlers and puppeteers?)
