Yes I saw it earlier on GT. It's interesting in concept no doubt, but like he himself said to make a big game like Call of Duty out of this would be overwhelmingly expensive (if at all possible). And wouldn't it take forever to load?
I do find it rather pretentious and stupid how he keeps comparing trees from Arma and Crysis to his own. There's dozens of different trees in Arma and Crysis. You guys made one.
