Oh...and following on from MrTeatime's post...
How many times have you heard in movies and books copies or variations on Churchills WWII speech? Or variations on the American "Independance" speech? It's not because they lack originality, but rather because they are great speeches full of inspiration!
You Americans should be proud that people the world over think that your Presidents "War on Terrorism" speech is so inspirational and worthy the history books, and being forever remembered even in the forms of Movies, books and yes...even games!! And really you should not be bashing anyone that thinks and does this just because they believe in what your President said...
