What did you expect from a game by a Russian company? Even if the game is 100x better than something made in the US during the whole year, it's still never going to be rated very high in the US (sadly). King's bounty is not the only such game this year. Take, for example Sublustrum (aka Outcry) or Collapse, or Turgor (aka Tension).
Ukraine and Poland aren't exactly Russia, but I think STALKER and The Witcher did make it to some GOTY rankings last year.
