God of War: Ascension may have cost as much to make as Modern Warfare 2, a modern touchstone of big budget development - or even more.more
Speaking to 20 Minuten, via Google Translate, lead producer Whitney Wade has said that Kratos's latest adventure had "a mid double-digit million amount".
A nice round ballpark figure, then, would be $50 million.
That's a pretty big number but not that unbelievable; Call of Duty: Modern Warfare 2 is believed to have cost between $40 and $50 million, with later entries probably even more expensive.
That's without the marketing budget, which can sometimes cost as much as development - or even more in the case of Modern Warfare 2's $200 million.
