Irrational Games founder Ken Levine has debunked "$200" million production cost rumor of BioShock: Infinite. Earlier today an unnamed analyst from NYTimes stated that the development cost of BioShock: Infinite is app. $200 million ($100M for marketing and $100M for the game development.)
On Twitter, Ken Levine debunked this and stated, "200 million for Infinite? Did someone send some checks to the wrong address?".
This means Irrational Games doesn't want anyone to know what exactly the budget was for BioShock: Infinite. We are also not interested in knowing, all i want is a great game and BioShock Infinite does look great.
