Because some games sells little compared to american, and others is a pretty mixed region, i suppose many games have a different release date for each country, and many games may stay at UK since it is the biggest Others market.

Well... It happens from time to time.

e.g. in Austria: Mana Khemia, Ar Tonelico were never released here.

Fragile Dreams was supposed to be released on the 19th, but we still don't have it.

I bet there are many other games, those are just a few I remember.

You can't be Austrian.... everyone knows there is only 1 gamer in Austria

Joking aside, what do you do when a game doesn't release there? German Amazon?

German Amazon? No, Amazon UK or eBay...

It is pretty strange to Austria don't get all releases, if i'm not mistaken all games of Europe are manufactured there.
