Gamezine: BAFTA explains the inclusion of the 2007 title, Call of Duty 4: Modern Warfare, in the 2008 Video Game BAFTA Awards, as well as the reasoning behind the limited nominations for Metal Gear Solid 4.
If you have a gander at the released nominations for the 2008 BAFTA Video Game Awards, you might find it odd that the game with the most nominations is Infinity Ward's Call of Duty 4: Modern Warfare - a 2007 game. This meant that 2008's Call of Duty: World at War was missing from the list.
