I played the demo over the weekend, I was not impressed. How people are hyping this game is beyond me. Though I guess if there's nothing else to hype, something is better than nothing . . .
I found it a repetive button masher, as mentioned before. Too much bloom lighting, while beautifully rendered faces, body detail suffers from low poly count. But the looks matter little in the heat of battle. Especially when you're trying your darndest to figure out how to be consistent with your hits. One time I did hit the 'B' button and grabbed a guy with the blade and swing him around killing everyone in the path, so that was a cool moment. It was also the end of the demo.
I don't know if the demo is indicative of the full game, but if it is its not worth $60.
