Then same happened with recent release of Assassin's Creed Unity game, except now on Steam store there has been no notification that this particular game will support only Russian language in RU\CIS.
This solution actually included you downloading pirated version of the game from torrent in order to extract the necessary language files and editing registry of you operating system.
Basically that fact stopped me from purchasing the game, until creative people posted a solution on how to unlock other languages (including English) for your game. First in my experience was Watch_Dogs title, there even was a notification by Steam that following game will support only Russian language for purchases in Russia and CIS countries. Lately there has been already 2 known to me attempts to region lock games Ubisoft has been releasing.
