Yes, I have played the Steam version. IMO the boardgame captures the essence of the videogame quite well. There are changes but they totally make sense, for example counting individual buildings or trees by hand would get annoying real quick so in the boardgame you count entire tiles. The way they handled the quest rewards extending the game is quite neat and smooth too. My partner liked the boardgame so much that she has started playing the Steam version too.
(note that this is based on a few early plays, not the entire campaign)
