Maybe...I would research cheaper and better ways to interface between the human body. You see, if we master those, we are one step from full immersive game experiences :D
If you think about the human body as a library, it's like a blackbox that have inputs and outputs. Inputs are our 5 senses: sight, hearing, smell, taste and touch. The most important outputs would be movement and speech, I guess.
We already exploit sight and hearing quite well. Given that smell is not that hard and taste is kinda negligible for a game, I believe it is possible TODAY to create a device of "full" virtual immersion. The hardest input would probably be the touch sense, but not at all impossible, given the state of human technology.
The real challenge would be the outputs. Speech is rather easy (with microphones), but movement is not. It could probably involve a device that could suspend a body and a suit capable of tracking it's movements (the tracking part already exists). The suit could also apply pressure on demand, to give inputs to the touch sense. I think it's already possible to create that, but it would be VERY expensive. Would probably feel very awkward too.
Another option for movement is "capturing" brain signals. This is also something that is possible today, but is not quite there yet (or we would be seeing lots of brain controlled prosthetic arms and legs around).
Well, the processing power to handle all those data is not something you can buy at eBay either. Computers would have to go a long way to make it accessible.
So, the thing is, if someone happens to find cheaper and better ways to interact with those body interfaces, we could be living in a game in no time! Maybe a couple hundred years from now :p
