I just downloaded and played the Infamous demo and I must say, if you liked the videos, you should LOVE the game. I'm posting about it, but I don't want to spoil anything specific about the demo for those who play, so excuse me if this seems a little vague. (We all knew you were going to LOVE it regardless, so let's just go huh-hum while reading this...)

Visuals

For visuals of the demo, I would say that they definitely support the artistic style that SuckerPunch were going for on the game. The cut scenes have the same comic book art style that the Sly Cooper games. Unfortunately, I don't have a HDTV (hmm, to be continued I guess) so I didn't get to see how great the visuals are on an HD spectrum but the game looked great on just SD. The greyish city sets the atmosphere and makes the villians and Cole just that much more distinguishable. (way too vague, tell us about animation, framerates, effects)

Gameplay

The climbing and the "flying" are really fun as well. I actually spent a few minutes just doing both of those things. It is way too easy to attach to certain objects but once you get the hang of it, it's awesome. You are good and evil at certain points, but I'm guessing that when you actually play the game, there will actually be fluctuation between the two depending on whether you do good or bad things for people. I personally just enjoyed shocking the hell out of everything. That's all I really needed to make me happy. (What? if that what sold you the game I'll stop reading right now. I need something a little deeper) I have to say, the powers are very fluid and easy to use. The GPS is very helpful. From the trailer at the end, there are a lot more powers available also it seems there is are ways to level up the powers you have in the demo, this isn't so much of a spoiler considering that the video is already available on Gametrailers.com. (how about challenge, is there any? do you get knocked down? do your powers ever run out? are the enemies something else than sitting ducks? Do any of the enemies have powers that can challenge yours or make some of your powers useless against them?)

Sound

Infamous so far has great sound in it. The music is very fitting for the mood of the game. The characters voice is rather raspy but seems to fluctuate throughout depending on whether he is good or evil. The people get repetitive when you are on a mission and it wants you to get the mission done, which can be annoying but otherwise I find it great. (hopefully, this will be good)

Overall

Overall, it's great, I can't wait until this game comes out and I hope that you guys like it as well. If anybody wants to leave their impressions, whether you love the demo or hate the demo, feel free to post in here. (just did)
