Odd, I've actually yet to have a game where America didn't do amazingly well. They always end up absorbing at least 2 other civs (usually cultural powerhouses and wonder spammers as luck would have it) before the Modern Era and growing out of control. They're my biggest roadblock to victory every time.
Last game that I had George in, he manged to eat up the three other Civs on the continent I spawned on. A couple of successful Classical and Medieval wars that snowballed into a curb stomping when he got his Minutemen.
He'll kick you apart, if you're not careful.
He did amazing in my last game and had more score than me at the end. I won as Ethiopia with a science victory. But still he had good science, every CS on his side and conquered Mongols, Austria and Denmark.I find that the American AI is too expansionist and just for his own good. The best aggressive civs are generally ultra cruel, exterminating their weakest, peaceful neighbors and stealing all their wonders, then snowballing out of control from there. America tends to pick fights with warmongers and end up in costly wars, generally forgoing the defenseless that have treated him kindly in the meantime. It's just a bad strategy. Ironically, Washington fights like American Revolution era redcoats - his notion of honor and fairness are so incompatible with the grotesqueries of war that it often gets him killed.
In addition, the amount of cities they place tends to anger everyone and make them a universal target, but economically, technologically, and diplomatically they have no meaningful special bonuses. Their UUs come late if at all and their strongest unit, the B52, the AI regularly sends to its death, using them like 3-use guided missiles and ignoring interceptors to boot.
Rarely a runaway.

A unique version of rugby football, American football became the most popular sport in the country in the latter half of the 20th Century. By the beginning of the 21st Century, there were over 100 American football stadiums seating 50,000 people or more, with several seating more than 100,000. The professional league's annual championship game, known as the Super Bowl, was watched by more than one hundred million people, in more than 30 countries.
