HOLY. FUCKING. SHIT.
This game is good. Damn good. The production values are amazing. If the game's budget really was $100 million (though Blizzard are trying to debunk the Wall Street Journal's original report of this figure - and WSJ have retracted the report, apparently), I think half of it went on the cinematics, because they're bloody incredible. The cutscenes are absolutely stunning - you can see the skin pores in people's faces, for frick's sake. Are videogame characters finally climbing out of the Uncanny Valley? Maybe.
It'll be another few days before I've played enough to review it properly, but everything I've seen so far says "two thumbs up".
