Shuhei Yoshida, president of Sony's Worldwide Studios, happened to be a panel speaker at DICE Summit 2015, which took place this week. Yoshida had some interesting thoughts on the state of current video games being released. According to Yoshida, sequels didn't always hold the reputation they do today. You weren't guaranteed solid earnings. These sequels were seen as wasted expenses, often not meeting the same amount of return as the original game.
However, the market changed. Sequels became less risky, and many publishing houses realized they could minimize risk and work load by annualising game franchises. Yoshida went to say that with all due respect to developers of major franchises he “hates” annualised releases and wish they wouldn’t happen.
I think when we look at games like Call of Duty, Assassin's Creed, and (unfortunately) Battlefield, it would be a lot better if we didn't get them so often. It's making the publisher money, they are sucking the franchise dry in fact, but the quality of the franchise drops after awhile and people become less excited about it.
