BTW
Look at that factor5 graph again. The explosive curve depicted is project staff, not costs. The costs are reported as labels under each data point. And sure, they increased alot, but in a much less explosive manner than that curve suggests.
For example the last bar is about double than the "Lair" one (+100%), but the costs are only about +33% more. And I think that a game published today can certainly collect revenue for more than a 33% differential with respect to 2007 (Lair time frame).
