I returned from the mana bar not too long ago... so I guess I'm just going to put my thoughts on the game here and some of the things that came out of my discussions with Randy and one of the marketing guys. There are also no surprises, it's the same demo as the one we've seen at PAX etc.
So anyway, about the game, overall I loved it. But it's not perfect...
The good:
* Feels like a rock solid FPS
* The AI seemed quite competent
* Duke's presence is quite strong in the game
* Lots of Duke speech (though it was so loud in the bar you couldn't actually hear what he says)
* Uses lots of graphical techniques like depth of field (although, see my comment in the bad stuff section since I'm coming back to this one).
* Very interactive... pretty much anything you see you can interact with. There is even a giant shit floating in one of the toilets, you can pick it up, carry it around and throw it at stuff
* The game is fun, and yes, it is definitely Duke... To me, this is the most important point, having played it, I do think this game will be awesome.
The bad:
* The biggest thing that bothers me is that the game content is noticeably dated. They're mainly relying on techniques like depth of field to hide it a bit, but when you're playing the game on a 40 inch screen up close, it really stands out to the point where it was quite painful to watch. While I wouldn't call it a show stopper, the game content doesn't look like something actually intended for release in 2011.
* The interactivity is very limited... For example: You can take a turd out of the toilet, but once you have it, it doesn't actually do much, if you throw it at something or someone, there's no splash or shit mark or anything, it just drops to the floor and leaves a stain there. Also, you can't take the white-board markers away from the white board and draw on the wall for example... so in many ways it's interactivity is quite localized. Having said that, I have not seen this level of interactivity since Duke 3D

* Extremely trigger driven... The game relies on you doing very specific things to continue the game. For example, I killed all the pigs on the second demo level and was just wondering around the level for a few minutes with nowhere to go and nothing to shoot. It's not all that obvious that you have to choose to 'use' the machine gun mounted to the floor to actually continue playing the game...
* The shadows are really grainy, I suspect they're using basic shadow mapping here
While not really gripes with the game itself, there were some other small annoyances as well:
* The game crashed on two different machines in the time I was there. While I'm sure they'll fix that by the time it ships, it does cause me to raise an eyebrow if it crashes even on their 'model' hardware...
* We had to play with game pads... Don't get me wrong, I love my 360, but an FPS needs to be played with a keyboard and mouse, a gamepad just doesn't cut it.
* No photos... no video is one thing, but at the mana bar we weren't even allowed to take photos. I've been told the mana bar's facebook page will host all the photos the staff took there though, which includes several shots of me for the ladies. Their facebook page is at: http://www.facebook.com/TheManaBar
* It was really really packed in there... the mana bar is not exactly big (about the size of my bedroom). Try fitting about a hundred people in your bedroom and you'll see the problem...
Now, I also got to talk to Randy and one of the T2 marketing guys, and essentially these are the main points:
* Randy doesn't know when they want to get the demo out, but they will announce it soon
* The guy from marketing thinks they will do it really close to the game's release in 2011 - which kinda sux considering they have a demo ready to go
* The February 1st release date is something amazon and co decided on by themselves but they are still targeting an early 2011 release.
* We can apparently expect the game to ship within the first half of 2011.
* When asking the guy from marketing about PlayStation move support, the answer I got was "I hope not!" - which isn't what I wanted to hear but that's how it is. I probably should have asked Randy the same question, but I forgot

So overall I really enjoyed it, I think it will be a good game despite some flaws. Also, I got two free t-shirts, so that's kinda cool
