Check this out, could you imagine how badass this would be? http://www.collegehumor.com/video/6583485/minecraft-in-hd
This would be AWESOME but it would never work. The reason you can build so "big" in MC compared to say the Sims is that it is light on effects.
Do you think it's really that far off? I mean, I've seen some pretty bad ass games on the PC that don't look like they're TO far behind those graphics. I mean, not that the average PC could run it, but could like a say Crysis 2 friendly computer do something like that?
^ Wait till they make hyper dense memory... HDM for short, this writing information on single atoms. Once they have done this they could then start making all the computer components out of this... i.e ram, gpu, cpu. That would then be one hell of a BEAST of a computer XD What would that be DDR1000000000000000 ram?
