Russian chatter is there as part zone atmosphere. Native russians dont speak english as first language :)
LOL, yes I know, I already had the three games, and very much enjoyed all the Russian background chatter. What I was referring to was the main dialogue. On these GOG versions, SOC and Clear Sky had English listed as the language in the download, and COP was listed as Russian.
However, today, the COP download says English, so issue solved. I am quite fine with a lot of the background voices being Russian, I enjoy it, but I was worried I would be lost on the dialogue if all of it was Russian.
