As I was organizing some of my Atari 2600 games, I was thinking about how far the gaming experience has progressed from 30 years ago. It's amazing to compare something like RiverRaid on Atari 2600 to a game like Crysis or MGS4, with the near photo-realistic graphics. I think few imagined 30 years ago or even 20 years ago what games would be like today. For example, 15 years ago it was widely assumed the the entire interface would change to some sort of immersive "virtual reality" experience with all sorts of headsets and the like, and that hasn't happened. On the other hand, I don't think that 15 years ago many would have imagined what it was like to play a 1080p first-person shooter on a huge plasma with full-surround sound.
So what do you think the NEXT 30 years will bring? Do you think the basic interface (TV/monitor) will change? Once absolute total photo-realism with respect to resolution, frame-rate, etc. will be achieved (some say we're already there) what direction do you think gaming will take? Will the 20-year old franchises (Castlevania, Zelda, MetalGear, Sonic) still be around in 30 years?
I can't help but imagine that a whole different type of experience will largely replace the media of video games, making this post something like asking, "what do you think the next 30 years will bring for VHS tapes" in the year 1980.
