Oh, wouldn't it be nice? I myself have the French Collector Edition - and it's my first TW game in other language than English... kinda bizzare, got to admit.

Some features aren't even translated..., merchants, for instance, trade in English: "...ce marchand vend du... silk", or "il vend du... iron" etc.

And in my French version, Aztecs address me with "sahib" and wish me "qu'Allah vous protege, sahib". Wow, Muslim Aztecs?

I couldn't find any means to change the in-game language...
