M&M: Heroes VI - Review @ GameSpy

GameSpy has reviewed Heroes VI, generally finding it a favourable experience but saying Ubisoft's Uplay DRM system nearly killed it for them (3/5):

Raising huge armies of gnarled fantasy creatures, thundering across the loot-laden countryside, and thrashing the kingdoms of rival heroes in epic turn-based battles is still every bit as awesome as it was when I first dove into Heroes of Might and Magic as a kid. Don't let the name switcheroo fool you: Might & Magic Heroes VI primarily sticks to the franchise's roots. It's laden with all of the excellent nitty-gritty details that strategic fantasy warfare nerds like me salivate over, but it also incorporates some updates to the formula that may not sit well with the hardcore set. As great as the underlying gameplay is, a few heinous design missteps nearly kill the experience outright, especially Ubisoft's hideous Uplay requirements.
