Scientifically, the fourth dimension is an idea. The literal sense that the fourth dimension might be dimension X is a sci-fi interpretation. Time itself is not the fourth dimension. The fourth dimension is a point in space at a certain time if my memory is correct without checking with the links provided. Not that any of it has anything to do with video games

The way I understood the 360's graphics platform vs the PS3's is that 360 is based on DX, which is a minimum common denominator in computer gaming. Which makes it easier to program for since its grounded by the standards instead of setting the standards like the PS3's platform is trying to do. PS3 has more potential but its harder to achieve. Or... something like that

No clue if either are capable of doing the Crysis thing 'cause I don't know anything about the Crysis games
