King’s Bounty: Воин Севера

I think this is a video for other countries. And it was made by someone who speaks English from the developers or testers. By the way, the buttons in the main menu were in English.

From 15 seconds to 59 seconds, the beginning of the game is shown, with Russian text. At 1:48, after receiving the quest, the text "QUEST LOG UPDATED" appears on the screen, as it should. The magic book is in Russian, and the dialogues in the castles are also in Russian.
