as was already mentioned DLC has helped Devs increase revenue without the core game price increases. Also there are alot more games being sold now days. So while the profit margin is lower, profits are higher. Also, the average game does not command a price of over 60, and the games that do typically have expansions, subsrsibtions, and DLC to equalize things (WOW, Elder Scrolls, COD, etc)
