Crysis hangs its success on DirectX 10 supergraphics, holy-s*** moments involving absolute-zero alien death machines, and possibly too-high technology -- but it hangs its hat on permutations. Pile custom weapon loadouts (no matter how nonsensical) on top of nanosuit configurations on top of everything-breaks physics, then add a layer of ice and toss it all into zero-g, and we've got n-factorial questions.... What happens when x + y is divided by z? What happens when you introduce w?
If Crysis is a collection of details from which complexity violently erupts, where's the limit? The Crytek crew pauses to bring Crysis' high concepts back to the ground, and to explain what could happen -- and what probably won't.
