They said that Gran Turismo 5 had a budget of $60 million in November of 2009, not mid-2008.
The Halo 3 numbers also look off, from what I recall.
The only numbers that look somewhat accurate are the figures for Killzone, FFXII, Shenmue, Too Human, and GTA.
This list is just bad all around. Not only are half the numbers questionable or downright wrong, but it doesn't include FFXIII or Red Dead Redemption.
