However Square managed the programmers for FFVII I don't know but the talent going into the various parts of this game is awesome. So many parts of the game programmed to work together in harmony.
Also, Braben's Frontier. For me that beats most 3D engines for genius in its day.
If we're talking about pure graphical eye-candy and environmental finesse, I'm with Crysis for the current wave of engines. Just looks amazing.
