Halo 3 needs an FoV boost as well. It's woefully limited.
This picture highlights the problem. Look how narrow and limited the field of view is. The yellow is standard, green is wide-screen, and the red and blue are split screen. Ideally, you'd love to have Halo 3 have the split screen field of view be standard for all players. Look how much more of the map you get up your FoV.
