Well, there was a very popular Swedish RPG called Drakar Och Demoner. The first edition was pretty much Worlds of Wonder in Swedish
. It's run to 6 editions and has changed a fair bit, how much resemblence to BRP it had by the 6th edition I don't know:

It seems to have a fairly big following and spawned a fair few supplements:

I don't speak or read Swedish so I don't know how much on the last link is official publications, fan produced or what. Nice artwork though. In fact if they could get the artist who did the artwork on the supplements on the last link to do some artwork for BRP I'd be well happy.
