And let's not forget that people who have never played Bioshock or Bioshock 2 will be more prone to purchase those games and any DLC available, which will give Take-Two even more money. (Assuming they buy new, which I doubt lol)

Let's see a high profile game that cost $60 and will sell atleast 2.5 million within a month. That is $150 million dollars. Let's assume that 1 million will buy the season pass. $20 * 1 million = $20 million. By the time all 3 DLC comes out, the game will have an additional 1.5 million with another additional 1 million buying the dlc. This complete total comes to around $290,000,000 million, and this does not include the little transactions for things like avatar and microtransactions. Therefore in it's lifetime, the game will approximately make $100 million in profit.
