Keep in mind, also, it was restarted 3 times. So lets say the number is 75 mil (i will never be able to find out the exact number, i just said the estimates I was given). Lets assume they get about 3/4s of the game done each time. The vast majority of cost is upfront (building the engine. assetts, voice acting, etc) and then marketing. Marketing never happened. But 3 projects coming to 75 mil at a studio that has delivered the god of war franchise isn't really that much money. 25 mil per reboot, or thereabouts.
And this is why I said Stig was "fat" that needed trimming.
