Aha, I see your point - apologies for misunderstanding.
Slightly OT, but for exactly that reason I think that in films/games they get rid of accented English if the actors are meant to converse in a foreign language - which is what they did in Valkyrie. Admittedly, then you'd have a lenghty debate about which 'flavour' of English to use!
Sorry for being 'special' - much searching didnt produce a link to the Russian sound files? Of course a nice GUI switch would be great, but I'd rather get technical now than wait X months of a patch!
