It's one of the best game of 2003 along with the first KOTOR. Add POP:SoT to that list.
As far as I know, there may not be a patch for the english version (yes, there's a word outside the US that also got this version. Surprising, isn't it?) because it was released so long after the original german version that all bugs were fixed by then. The last patch for Gothic2 was out 15.03.03, the 'internationnal' version was out on 06-13-03. In other words, try to make up real complain next time... That lack of 'internationnal' for the expension pack was a let down though.
