He is saying he is limiting his career, not becoming unemployable. Projects like CoD, BF or Halo offer, by far, more money, stability, professional development possibility, sane working environment etc. There are plenty of studios that never have made and never will make an FPS. There are plenty of people who never shipped an FPS in their entire career. However, in the current market, if you are not working on an FPS like mentioned above, chances are high that you are crunching for low pay, over a design made by people who don't even want to play the game themselves, surrounded by peers who hate their job and either having the project canceled and laid-off or shipping a mediocre game and getting laid-off in lieu of completion bonus.
