Just a quick note - please keep this from becoming a Europe vs. America argument, or it'll get closed. It hasn't got there yet, but it has veered towards it in a few places.
And now on to the subject at hand....
For what it's worth, I noticed far, far less difference travelling from England to America than I have travelling from just England to France, let alone Italy or elsewhere in Europe. The US just seemed like home but with tips and funny accents; other countries in Europe feel much more different. I think that the language thing outweighs pretty much any other factor when you're talking about cultural changes between countries.
