Ah yes, that nagging feeling at the base of my skull was there for a reason: there was a demo of Might & Magic Heroes VI released this weekend. A portly 4.24gb download (some 22,000 Peggles, if my maths be remembered correctly) contains three campaign maps from the full game, and therefore a decent chunk of game time.
Why not have a read of Alec’s preview of the full game here, and then carefully make a list of how his opinion differs from yours? That would be a strange thing to do. The game is out on October 13th.
