Is it EA or just how game studios work? Historically, studios either put out zero games or one game. I think it's the fairly extreme outliers that do it over and over and most of them deal in sequels. If you look inside the game industry, I think I would be hard pressed to do a second game if I made games. It doesn't look like an easy feat to keep the team magic working. Likewise, there seems to be no shortage of up and comers that want to make a new game. The studio might not be as valuable as we want to think. Which would you bet more money on: Maxis coming up with a new hit game concept or the masses going ape over sim city 2015 on ps4? And by "ape" I mean willing to buy it for over $30. I have a hard time with both options, just like ea.
