No PC Release
As of 2009, Call of Duty 3 has not been released for the PC format. For this reason, Call of Duty 3 is considered the odd man of the franchise. It is the only COD game released on Xbox 360, Playstation 3 and Wii.
Multiplayer Classes
Moving away from the traditional Call of Duty system multiplayer system, COD3 introduced the class-based system that is still being used. This gives players more input over the direction of their character.
Wii Version
Because of the limited functionality of the Wii remote, some might find it easier to use the Classic Controller instead of the default configuration.
Single Player
The single-player campaign is regarded as one of the weakest in the series, largely because of its average completion time of four hours.
Wii Hardware
Unlike other versions, the Wii version experiences considerable slowdown during more intense scenes in the game.
PS3 Keyboard
The PS3 version supports a keyboard configuration as well as the standard controller configuration.
