Zach Whalen at Gameology played Al Qaeda's Night of Bush Capturing (aka Quest for Bush) and wrote this excellently detailed comparison to the original game from which it's adapted, the 2003 American game Quest for Saddam. Writes Whalen:
Even calling it a mod is, I think, pretty generous considering how little work (relatively speaking, of course) went into creating Quest for Bush from the Quest for Saddam source material. What I think is important and interesting about both games, however, is the way their programmatic relationship reveals an underlying logical similarity between the anti-Saddam and anti-Bush messages. [...] Quest for Bush simply switches the variables on an already political (and probably xenophobic) game's content.
The info Whalen dug up about Jesse Petrilla, the maker of Quest for Saddam, is rich stuff:
Petrilla created Quest for Saddam in 2003 as a kind of sequel to Quest for Al-Qa'eda, perpetuating the conflation of the Iraq War with the War on Terror and continuing the pattern of attempting to derive humor from stereotypes of Arabs. Since 2003, Petrilla seems to have continued his Islam-related activism by founding the United American Committee (UAC), a political action group focused on "promoting awareness of Islamist extremist threats in America." On September 10th, they hung Osama bin Laden in effigy in front of a mosque in Culver City, CA.
Whalen also notes that Petrilla's United American Committee's website is offering downloads of Quest for Saddam for free so you folks at home can compare for yourselves.
