I'm with Rarehero, I don't enjoy bashing things, I just feel like the best approach is honesty. I was at Expo, I experienced the game in person, and it's just not something that felt good.
In an effort to be constructive though, here's my "realistic" (meaning no wild changes) list of things I'd love to see addressed just to make the presentation stronger:
1) The spinning Smaug isn't working for me. Mainly because the back of him, the "mountain", is just super boring and bland, and that's what you see 95% of the time. And the area around it feels empty and weird.
So I would either just lose the spinning and have the sculpt always visible, maybe with some kind of "sleeping" thing going, like a slowly pulsing LED light or the like, or I would totally rethink the "mountain" side. Make it something cool to look at when there's no dragon. What if instead it was the doorway that the map helped them find, and it has LED lighting to make the outline and runes around it pulse?
And fix the area around the whole mech to not look so empty and strange. The rest of the mountain perhaps. Also the coins in the sculpt are way too big. It makes the dragon look puny and small. No need to change the dragon, just make the coins in the pile smaller.
When he's actually talking it's cool, I don't think it's a bad idea at all, but it's just so rare that you get this "that's it?" feeling from him. And that's on top of the "doesn't interact with the ball" aspect.
Maybe there's more to be revealed there, that's my impression of the things as shown.
2) The VUKs are just awful looking, very industrial. Replace them with wireforms. No idea what the cost difference would be, it can't be big, and you wouldn't have to print decals and apply them. The ball flying up wireforms, fully visible, would look 500% better. If that creates some issues with things not being hidden or something then find another solution for hiding them.
3) The metal ramps in the middle are really unappealing looking. I heard they might get decals. My suggestion is if you're going to have metal ramps then do something that metal is good at. Laser cut them with some runes or designs. The metal ramps on Metallica are way cool with the M laser cut in. Make the sides where the ball doesn't roll look cool.
I can't tell if the diverter is really supposed to be his tail or if Jack just made that up. But right now it's a chunk of metal. If it's supposed to be a tail we need a sculpt or something to make that work.
4) The drop targets are the big feature of the game. I'd like to see decals or something on the standups behind them, make it so when you drop the target to reveal the standup behind it like you're revealing more. The color of the drop and standup was a little too close, low contrast, made the feature not pop enough.
5) The book! It's just weird. If it's not a placeholder decide it is one. It's open half way to show the beginning, which makes no sense, and it's just visually unappealing and odd. First you have a dragon with big coins that looks like a large dog, and then there's a giant book, that's like the same size as Smaug. Feels super weird. I thought we'd get a sculpt of bag end at least. I think most people were expecting that with an LCD screen replacing the door. Would have been so much cooler. If the LCD isn't possible maybe Bilbo's house at least is? You had a freaking spinning house in WOZ, and an LCD toy! Come on, you can't sell this game for as much or more and have less.
Those are my off the top of the head thoughts about what I'd love to see get more attention, without a total redesign, which is obviously not practical.
