Powerful weak. I'm not sure how it could have been an entire gigabyte, because there's nothing to it. A brief, God of War-like button-pushing sequence, and then two, er, God of War-like melee battles. Then it just stops. Total play time is probably three minutes. The combat seemed like pure button mashing, although certainly it's hard to experiment in the brief time the demo gives you. All in all, I don't know why they bothered releasing this. Isn't the point of a demo to get people excited about a game?
