In 2007 we got Halo 3, COD 4 Modern Warfare and Bioshock. I wasn't big on Halo 3, but many people were, COD 4 is my favorite COD and Bioshock is one of my very favorite games of all time. Gonna be hard to top that year for me regarding fps'.

Another good answer; that year saw the release of Crysis and The Darkness as well, both of which I thought were damn good.
