Hmm, ok, i'll take that back, was pretty sure there were some. In any case, you can't deny that the vast majority of video games, that involve some sort of warfare, whether historical or fictional, tend to portray US as some sort of guardian angel of all things good, which is a form of propaganda too.
These games also aren't created or funded by the Government, and even the ones that are (America's Army) don't portray the USA as the "guardian angel of all things good". America's Army 3 was set in your typical U.S intervention over a smaller country's internal problems. And even then, the gameplay itself was advertisement for the actual meaning behind the game itself, as it was made to educate people on the "standard and beliefs" of the U.S Army.
However, games like Call of Duty often portray the U.S as the good guys do so because it's just easier. It's simple to go "U.S good guys" because the largest portion of their market is in the U.S itself, and everybody knows American's are patriotic and love to see their own country in a positive light.
Shit, even the newest America's Army basically portrays the entire game as "war games" or training missions, what with the simunition (paint rounds) and all that.

I like to "quote" things.
