The future is always an exciting place, and these days you just don't know WHAT will be next. Already, we have motion-sense technology (Wii) and computers small enough to fit on one's palm (Ipod Touch).
Here's a fun activity for you all- devise a futuristic game console that could "work" and be at least somewhat marketable. Share them with us on this page!
As for me, I've always thought a gaming system based on dreams would be an enchanting and enjoyable experience. Games could be played mentally, while you're asleep. The technology probably wouldn't exist in our lifetime, but with the advancement of electronic technology I believe it is a possible concept. I would suspect Nintendo would make it, since they believe in full-front interactivity these days.
