The big English gaming sites are taking their time to review Heroes VI. GameSpy is the first to publish its review in which they praise the familiar turn-based gameplay but highlight the visual bugs and UPlay online requirements. Here is the bottomline:

"If I wasn't punched in the face by UPlay every time Heroes VI's engaging campaigns get rolling, I'd be in love. There's a great game hiding underneath the wet blanket of visual glitches and connectivity issues. Heroes VI strikes the right balance between subtle innovation and faithfulness to the core elements that make the series so excellent, but the experience is nearly ruined by the poorly implemented online infrastructure."

GamePro has a review as well here. In both case the final score is 3 out of 5. Let's wait and see what GameSpot and Eurogamer have to say now.
