InfraSuperman: The general argument from German officials is that, due to its appropriation by the NSDAP, any variation of the symbol is "burdened" by those connotations and any depiction might be misunderstood as Nazi propaganda.
It's actually kind of funny to see how the German government is always walking on eggshells when it comes to Religions such as Islam and Judaism, always desperately flailing to not offend anyone, only to then turn around and piss all over an important symbol for Hindus and Buddhists. In 2005, Germany suggested a Europe-wide ban of the symbol to the EU. They only dropped it after British Hindus protested.
"We stole one of your sacred symbols and perverted it in the minds of millions. In lieu of an apology, please accept this international ban."
Awesome.
j0ekerr: The most obvious difference was the framerate which had to do with distributed electric current cycles if I remember corectly, being different in america to those of europe.
And number of scanlines. I remember playing UK games on my US Amiga. They worked fine, except for some wonky vertical display issues.
But yes, most of those issues are being relegated to the past, thanks to new digital formats. And since a lot of material is going back and remastering from the source, the televisual formats are even less relevant.
