Typically when talking about imports, particularly imports of JRPG's, I always assume most of them come from Japan, not Europe, hence the name "JRPG." You're talking about one specific game that was translated for countries in Europe. I'm talking about imported JRPG's in general.
You must be new to this.
The large large gap between release dates in the Japan -> America -> Europe means that Europeans (and other PAL users) importing from America to Europe is not that uncommon.
The PS3, DS (not 3DS) for example have absolutely enormous import markets simply because they're not region locked. The other is of course on price.
As an Australian (Who is in a PAL region) I have imported more than half of the games I own simply due to reasons of cost and release date.
Exactly this. There are many people importing from America to Europe and Europe to America.
"The Arcana is the means by which all is revealed."
One of them is that without it, people could import titles from overseas and play it on their region's machines. This doesn't sound bad in theory, but when currency exchanges vary as wildly as they do now, it would mean that without region locking, Japanese consumers would import every game possible from the US or Europe because even with shipping the cost would be less due to the current exchange rate.
Actually, that's the main reason. Region locking exists to ensure that sales for software and hardware remain locked to that region's currency, otherwise, savvy shoppers would flock to importing from regions with cheaper currencies, resulting in smaller margins for the game/hardware creators.
